| 4 | Recent advances in photofunctional polymorphs of molecular materials显示文摘Recently,molecule-based luminescent materials have been drawing extensive attention due to their desirable properties and promising applications in the fields of sensors,lighting display and cell imaging.Crystalline polymorph is an intriguing phenomenon that the presence of multiple packing and aggregate architectures of the same molecular system.The studies on polymorphs for molecule-based fluorophores provide the opportunities to adjust the mode of molecular packing and photophysical properties,which will help to illustrate the structure-property relationship.In this review,we focus on the recent progress in various feasible methods of molecule-based crystalline polymorphism growth and their adjustable photofunctional properties,which will open up possibilities of variant optical applications.Firstly,several effective ways to prepare and screen polymorphs are sorted out.And then,we discuss the discrepant properties and multifunctional applications(such as sensors,laser and OFET).Finally,the development trends and future prospects of these polymorphs are also briefly introduced. | Bo Lu Shuya Liu Dongpeng Yan | 2019 | Chinese Chemical Letters2019，30，11： | 5 |
| 5 | 带并联电抗器的交流特高压输电线路单相自适应重合闸故障识别方法(英文)显示文摘In order to avoid single-phase adaptive reclosure overlap in a permanent fault,accurate identification of the fault types on transmission line is necessary.We present a fault nature identification method for ultra-high voltage alternating current(UHVAC) transmission lines with shunt reactor.The voltage amplitude ratios of the neutral small reactance voltage to terminal voltage under transient fault and permanent fault are calculated.The significant differences of the ratio under the two faults have been analyzed.It is found that the ratio can be a criterion to distinguish the fault type,transient or permanent,accurately.Additionally,we also proposed a method that delays a beat frequency oscillation cycle to decide the fault types for the existence of beat frequency oscillation which will cause misidentification on transient faults.Abundant simulation results of ATP/EMTP show that the voltage amplitude ratio under transient fault is between 0.6 and 0.7,which is bigger than 2.5,the ratio under permanent fault. | LIN Xin XIE Yinzhi SUI Dongpeng XU Jianyuan LIU Yang | 2013 | 高电压技术2013，39，4： | 4 |

| 7 | Room-Temperature Phosphorescent Organic-Doped Inorganic Frameworks Showing Wide-Range and Multicolor LongPersistent Luminescence显示文摘Long-persistent luminescence based on purely inorganic and/or organic compounds has recently attracted much attention in a wide variety of fields including illumination,biological imaging,and information safety.However,simultaneously tuning the static and dynamic afterglow performance still presents a challenge.In this work,we put forward a new route of organic-doped inorganic framework to achieve wide-range and multicolor ultralong room-temperature phosphorescence(RTP).Through a facile hydrothermal method,phosphor(tetrafluoroterephthalic acid(TFTPA))into the CdCO_(3)(or Zn_(_(2))(OH)_(2)CO_(3))host matrix exhibits an excitation-dependent colorful RTP due to the formation of diverse molecular aggregations with multicentral luminescence.The RTP lifetime of the doped organic/inorganic hybrids is greatly enhanced(313 times)compared to the pristine TFTPA.The high RTP quantum yield(43.9%)and good stability guarantee their easy visualization in both ambient and extreme conditions(such as acidic/basic solutions and an oxygen environment).Further codoped inorganic ions(Mn_(2)+and Pb_(2)+)afford the hybrid materials with a novel time-resolved tunable afterglow emission,and the excitation-dependent RTP color is highly adjustable from dark blue to red,covering nearly the whole visible spectrum and outperforming the current stateof-the-art RTP materials.Therefore,this work not only describes a combined codoping and multicentral strategy to obtain statically and dynamically tunable long-persistent luminescence but also provides great opportunity for the use of organicinorganic hybrid materials in multilevel anticounterfeiting and multicolor display applications. | Guowei Xiao Bo Zhou Xiaoyu Fang Dongpeng Yan | 2021 | Research2021，，1： | 4 |
| 8 | Intercalation assembly of kojic acid into Zn-Ti layered double hydroxide with antibacterial and whitening performances显示文摘A melanin synthesis inhibitor and bacteriostatic agent, kojic acid(KA) has been intercalated into Zn-Ti layered double hydroxide(LDH) by an anion-exchange reaction. The structure and the thermal stability of the samples were characterized by XRD, FT-IR, TG-DTA and SEM. The study of KA release from ZnTi-KALDH in phosphate buffered solution(pH 5) implies that ZnTi-KA-LDH is a better controlled release system than pure KA. Meanwhile, the mechanisms of slow release were assessed by using four commonly kinetic models. The antimicrobial activity of ZnTi-KA-LDH was tested against three kinds of bacteria. The inhibition of L-dopa oxidation was tested to verify its skin whitening effect. The studies suggest that the kojic acid intercalated LDHs has the potential application as a safely functional composite in cosmetic. | Xin-Rui Wang Hui-Min Cheng Xue-Wei Gao Wei Zhou Shu-Jing Li Xue-Li Cao Dongpeng Yan | 2019 | Chinese Chemical Letters2019，30，4： | 3 |
| 9 | A reversible acid-base fluorescent switch based on molecular cocrystal of 4-[2-4-quinolinyl)vinyl]phenol and tetrafluoroterephthalic acid显示文摘Photoactive cocrystal materials have received growing research interest in construction of photofunctional systems owing to the crucial roles in modifying the photo-related properties of molecular solids, based on the non-bonding interactions between self-assembly units. Herein, we report tunable luminescence and acid-base stimuli-responsive properties of a cocrystal assembled by 4-[2-(4-quinolinyl)vinyl]phenol (qv) and tetrafluoroterephthalic acid (a). The luminescent properties (such as wavelength, quantum yield and fluorescence lifetime) of qv.a changed obviously relative to the pristine qv, due to the proton transfer and the alternation of molecular arrangement within two-component crystalline material. The photoemission intensity of qv.a underwent from weak to strong upon HCl gas fuming, and the corresponding wavelength changed from 517 nm to 597 nm, which can be reversibly transferred after exposed in NH3. Such luminescent switching behavior may provide an effective way to develop new types of photoactive stimuli-responsive materials and optical sensors. | Shuzhen Li Dongpeng Yan | 2018 | Science China Chemistry2018，61，2： | 3 |
| 10 | White-light emission and tunable room temperature phosphorescence of dibenzothiophene显示文摘Molecular materials exhibiting room temperature phosphorescence(RTP) have received much attention during last few years. It has been known that different stacking fashions(e.g., formation of polymorph) and aggregation/crystal states could largely influence the RTP efficiency. However, whether the crystal morphology or shape could play a key role in modulation of the RTP has not been detected yet. In this work, we report that the dibenzothiophene(DBT) with the same molecular stacking fashion but different crystal morphologies can present alternated RTP performances. By modulation of the fluorescence and phosphorescence dual emission, a direct warm-white color light-emitting has also been successfully achieved. Moreover, the RTP emission can be further tuned through hybridization with β-cyclodextrin in different ratios, with the longest lifetime of 0.43 s. | Xiaoyu Fang Dongpeng Yan | 2018 | Science China Chemistry2018，61，4： | 3 |

| 12 | New flame retardant epoxy resins based on cyclophosphazene-derived curing agents显示文摘To obtain high-efficiency flame retardancy of epoxy resins,a cyclophosphazene derivative tri-(ohenylenediamino)cyclotriphosphazene(3 ACP)was successfully synthesized and used as a curing agent for the thermosetting of an epoxy resin system.The flame retardant properties,thermal stability,and pyrolysis mechanism of the resultant thermosets were investigated in detail.The experiments indicated that the synthesized thermoset achieved a UL-94 V-0 rate under a vertical burning test as well as a limiting oxygen index(LOI)of 29.2%,which was able to reach V-0 even when a small amount of 3 ACP was incorporated.Scanning electronic microscopic observation demonstrated that the char residue of the thermosets was extremely expanded after the vertical flame test.Thermal analysis showed that the samples had a lower initial decomposition temperature when 3 ACP was introduced into the epoxy resin systems.This indicates that the carbonization ability of the thermosets was significantly improved at elevated temperatures.In addition,the incorporation of 3 ACP can effectively suppress the release of combustible gases during the pyrolysis process,and the decomposition of E-44/DDS-3 ACP curing systems also promotes the formation of polyphosphoramides charred layer in the condensed phase.The investigation on the chemical structures of both the gaseous and condensed phase pyrolysis process confirmed the flame-retardant mechanism of the 3 ACP-cured epoxy resins.Therefore,the nonflammable halogen-free epoxy resin developed in this study has potential applications in electric and electronic fields for environment protection and human health. | Zhenwei Miao Dongpeng Yan Xiaodong Wang Xinfang Zhang Wenqi Zhou Munan Qiu Fan Yang Zhanpeng Wu | 2022 | Chinese Chemical Letters2022，33，8： | 3 |
| 13 | Towards single-atom photocatalysts for future carbon-neutral application显示文摘The implementation of carbon neutrality to achieve the goal of controlling global warming in the Paris Climate Agreement is currently the most important international climate issue.Efficient utilization of solar energy through photocatalysts is of great significance to the adjustment of energy structure.Single-atom photocatalysts have excellent catalytic activity and selectivity in a variety of applications,including sustainable energy conversion,chemical synthesis,CO_(2)reduction,environmental remediation,and other areas,owing to their unique electronic structure and high atom usage.Here,we elaborated on the content and implementation direction of the carbon neutrality policy and demonstrated the design principles of single-atom photocatalysts.Recent single-atom synthesis strategies are summarized,and representative characterization methods have been shown to further reveal the structure–performance relationship.Then,we focus on the application of single-atom photocatalysts in CO_(2)reduction,sustainable energy conversion,and environmental remediation.Finally,the opportunities and challenges in the application of single-atom photocatalysts were discussed based on its current development. | Dongpeng Zhang Yanxiao Li Yi Li Sihui Zhan | 2022 | SmartMat2022，3，3： | 2 |
| 14 | The passivation mechanism of Fe in the acidic AlCl_3-EMIC ionic liquid显示文摘The passivation behavior of Fe in the acidic AlCl_3-1-ethyl-3-methyl-imidazolium chloride(AlCl_3-EMIC) ionic liquid was studied by linear sweep voltammetry and chonopotentiometry. Various approaches were used to characterize the composition and morphology of passive film formed on the Fe electrode, such as scanning electron microscopy(SEM), Raman spectra and X-ray Photoelectron Spectroscopy(XPS). The results showed that the critical passivation potential of Fe shifted to more negative when the molar ratio of AlCl_3:EMIC changing from 2 to 1.3.A film with a light yellow color was observed on the surface of the Fe electrode after passivation. The composition of the passive film was demonstrated to be FeCl_2. The passive film was composed of particulate FeCl_2 with average diameter of about 500 nm. The formation of FeCl_2 film was attributed to the variation of the electrolyte Lewis acidity from acidic to neutral at the interface during the dissolution process of Fe. The reason caused the variation of the electrolyte acidity was discussed. | Dongpeng Xue Yang Yang Guoping Ling | 2017 | Green Energy & Environment2017，2，4： | 2 |
| 15 | Promoting electrochemical conversion of CO2 to formate with rich oxygen vacancies in nanoporous tin oxides显示文摘Defect engineering,especially oxygen vacancies(O-vacancies) introduction into metal oxide materials has been proved to be an effective strategy to manipulate their surface electron exchange processes.However,quantitative investigation of O-vacancies on CO2 electroreduction still remains rather ambiguous.Herein,a series of nanoporous tin oxide(SnOx) materials have been prepared by thermal treatment at various temperatures and reaction conditions.The annealing temperature dependent Ovacancies property of the SnOx was revealed and attributed to the balance tunning of the desorption of oxygen species and the continous oxidation of SnOx.The as-prepared nanoporous SnOx with 300℃treatment was found to be highest O-vacant material and showed an impressive CO2 RR activity and selectivity towards the conversion of CO2 into formic acid(up to 88.6%),and superior HCOOH incomplete current density to other samples.The ideal performance of the O-vacancies rich SnOx-300 material can be ascribed to the high delocalized electron density inducing much enhanced adsorption of CO2 with O binding and benefiting the subsequent reduction with high selectively forming of formic acid. | Tengfei Gao Anuj Kumar Zhicheng Shang Xinxuan Duan Hangchao Wang Shiyuan Wang Shengfu Ji Dongpeng Yan Liang Luo Wen Liu Xiaoming Sun | 2019 | Chinese Chemical Letters2019，30，12： | 2 |
| 16 | Selective formation of luminescent chiral cocrystal:Molecular self-assembly of 2,20-binaphthol and 2-(3-pyridyl)-1H-benzimidazole显示文摘Luminescent cocrystals have been received much attention in fluorescence imaging and sensor application. In this work, we report that the high-quality chiral luminescent cocrystal can be obtained through a molecular self-assembly process of 2,20-binaphthol and 2-(3-pyridyl)-1 H-benzimidazole. The assembly modes and stacking fashions of as-obtained cocrystal were determined by single crystal X-ray diffractometer. The structure and optical properties of the cocrystals were characterized by fluorescence emission, fluorescence decay, Raman and circular dichroism spectra. The results show that both the pristine co-assembled units(R-BINOL and S-BINOL) give rise to the R conformation within the final cocrystal, suggesting that the formation of cocrystal can be an effective way to achieve R/S-isomeric transformation of 2,20-binaphthol. It is also expected that the co-crystallization approach has much flexibility and potential applications for the design and selective formation of chiral luminescent materials. | Yanluo Lu Yanqun Tang Heyang Lin Xiaoyu Fang Bo Lu Dan Li Dongpeng Yan | 2018 | Chinese Chemical Letters2018，29，10： | 1 |
| 17 | Highly active sites of NiVB nanoparticles dispersed onto graphene nanosheets towards efficient and pH-universal overall water splitting显示文摘Production of hydrogen(H2) and oxygen(O2) through electrocatalytic water splitting is one of the sustainable,green and pivotal ways to accomplish the ever-increasing demands for renewable energy sources,but remains a big challenge because of the uphill reaction during overall water splitting.Herein,we develop high-performance non-noble metal electrocatalysts for pH-universal water splitting,based on nickel/vanadium boride(NiVB) nanoparticles/reduced graphene oxide(rGO) hybrid(NiVB/rGO)through a facile chemical reduction approach under ambient condition.By virtue of more exposure to surface active sites,superior electron transfer capability and strong electronic coupling,the asprepared NiVB/rGO heterostructure needs pretty low overpotentials of 267 and 151 mV to deliver a current density of 10 mA cm^(-2) for oxygen evolution reaction(OER) and hydrogen evolution reaction(HER)respectively,with the corresponding Tafel slope of 44 and 88 mV dec^(-1) in 1.0 M KOH.Moreover,the NiVB/rGO electrocatalysts display a promising performance in a wide-pH conditions that require low overpotential of 310,353 and 489 mV to drive a current density of 10 mA cm^(-2) for OER under 0.5 M KOH,0.05 M H2SO4 and 1.0 M phosphate buffer solution(PBS) respectively,confirming the excellent electrocata lytic performance among state-of-the-art Ni-based electrocatalysts for overall water splitting.Therefore,the interfacial tuning based on incorporation of active heterostructure may pave a new route to develop bifunctional,cost-effective and efficient electrocatalyst systems for water splitting and H2 production. | Muhammad Arif Ghulam Yasin Muhammad Shakeel Muhammad Asim Mushtaq Wen Ye Xiaoyu Fang Shengfu Ji Dongpeng Yan | 2021 | Journal of Energy Chemistry2021，30，7： | 1 |

| 20 | Memory access integrity:detecting fine-grained memory access errors in binary code显示文摘As one of the most notorious programming errors,memory access errors still hurt modern software security.Particularly,they are hidden deeply in important software systems written in memory unsafe languages like C/C++.Plenty of work have been proposed to detect bugs leading to memory access errors.However,all existing works lack the ability to handle two challenges.First,they are not able to tackle fine-grained memory access errors,e.g.,data overflow inside one data structure.These errors are usually overlooked for a long time since they happen inside one memory block and do not lead to program crash.Second,most existing works rely on source code or debugging information to recover memory boundary information,so they cannot be directly applied to detection of memory access errors in binary code.However,searching memory access errors in binary code is a very common scenario in software vulnerability detection and exploitation.In order to overcome these challenges,we propose Memory Access Integrity(MAI),a dynamic method to detect finegrained memory access errors in off-the-shelf binary executables.The core idea is to recover fine-grained accessing policy between memory access behaviors and memory ranges,and then detect memory access errors based on the policy.The key insight in our work is that memory accessing patterns reveal information for recovering the boundary of memory objects and the accessing policy.Based on these recovered information,our method maintains a new memory model to simulate the life cycle of memory objects and report errors when any accessing policy is violated.We evaluate our tool on popular CTF datasets and real world softwares.Compared with the state of the art detection tool,the evaluation result demonstrates that our tool can detect fine-grained memory access errors effectively and efficiently.As the practical impact,our tool has detected three 0-day memory access errors in an audio decoder. | Wenjie Li Dongpeng Xu WeiWu Xiaorui Gong Xiaobo Xiang Yan Wang Fangming gu Qianxiang Zeng | 2019 | Cybersecurity2019，2，1： | 1 |
