| 1 | Nitrogen-doped carbon nanotube/polyaniline composite:Synthesis, characterization, and its application to the detection of dopamine显示文摘Nitrogen-doped carbon nanotubes (N-CNTs)/polyaniline (PANI) composites are developed as an electrode material for biosensors. The morphology, composition, and optical properties of the resulting products were characterized by transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), and ultraviolet-visible absorption spectra (UV-vis). Furthermore, N-CNTs/PANI composite was immobilized on the surface of a glassy carbon electrode (GCE) and applied to construct a sensor. The obtained N-CNTs/PANI-modified GCE showed one pair of redox peaks and high catalytic activity for the oxidation of dopamine (DA) in a neutral environment. Differential pulse voltam-mograms results illustrate that the fabricated DA biosensor has high anti-interference ability towards ascorbic acid (AA). In addition, the fabricated biosensor showed superior performances with two wide linear ranges from 1 to 80 μM and from 1.5 to 3.5 mM and a low detection limit of 0.01 μM. | FENG XiaoMiao LI RuiMei MA YanWen CHEN RunFeng MEI QunBo FAN QuLi HUANG Wei | 2011 | Science China Chemistry2011，54，10： | 3 |
| 2 | MOF-Like 3D Graphene-Based Catalytic Membrane Fabricated by One-Step Laser Scribing for Robust Water Purification and Green Energy Production显示文摘Increasing both clean water and green energy demands for survival and development are the grand challenges of our age.Here,we successfully fabricate a novel multifunctional 3D graphene-based catalytic membrane(3D-GCM)with active metal nanoparticles(AMNs)loading for simultaneously obtaining the water purification and clean energy generation,via a“green”one-step laser scribing technology.The as-prepared 3D-GCM shows high porosity and uniform distribution with AMNs,which exhibits high permeated fluxes(over 100 L m^(−2) h^(−1))and versatile super-adsorption capacities for the removal of tricky organic pollutants from wastewater under ultra-low pressure-driving(0.1 bar).After adsorption saturating,the AMNs in 3D-GCM actuates the advanced oxidization process to self-clean the fouled membrane via the catalysis,and restores the adsorption capacity well for the next time membrane separation.Most importantly,the 3D-GCM with the welding of laser scribing overcomes the lateral shear force damaging during the long-term separation.Moreover,the 3D-GCM could emit plentiful of hot electrons from AMNs under light irradiation,realizing the membrane catalytic hydrolysis reactions for hydrogen energy generation.This“green”precision manufacturing with laser scribing technology provides a feasible technology to fabricate high-efficient and robust 3D-GCM microreactor in the tricky wastewater purification and sustainable clean energy production as well. | Xinyu Huang Liheng Li Shuaifei Zhao Lei Tong Zheng Li Zhuiri Peng Runfeng Lin Li Zhou Chang Peng Kan-Hao Xue Lijuan Chen Gary J.Cheng Zhu Xiong Lei Ye | 2022 | Nano-Micro Letters2022，14，11： | 2 |

| 4 | Near-Infrared-Excitable Organic Ultralong Phosphorescence through Multiphoton Absorption显示文摘Organic ultralong room-temperature phosphorescence(OURTP)with a long-lived triplet excited state up to several seconds has triggered widespread research interests,but most OURTP materials are excited by only ultraviolet(UV)or blue light owing to their unique stabilized triplet-and solid-state emission feature.Here,we demonstrate that near-infrared-(NIR-)excitable OURTP molecules can be rationally designed by implanting intra/intermolecular charge transfer(CT)characteristics into Haggregation to stimulate the efficient nonlinear multiphoton absorption(MPA).The resultant upconverted MPA-OURTP show ultralong lifetimes over 0.42 s and a phosphorescence quantum yield of~37%under both UV and NIR light irradiation.Empowered by the extraordinary MPA-OURTP,novel applications including two-photon bioimaging,visual laser power detection and excitation,and lifetime multiplexing encryption devices were successfully realized.These discoveries illustrate not only a delicate design map for the construction of NIR-excitable OURTP materials but also insightful guidance for exploring OURTP-based nonlinear optoelectronic properties and applications. | Ye Tao Lele Tang Qi Wei Jibiao Jin Wenbo Hu Runfeng Chen Qingqing Yang Huanhuan Li Ping Li Guichuan Xing Quli Fan Chao Zheng Wei Huang | 2020 | Research2020，，1： | 1 |
| 5 | Interfacial Assembly Directed Unique Mesoporous Architectures:From Symmetric to Asymmetric显示文摘CONSPECTUS:Functional mesoporous materials have experienced flourishing developments over the past 30 years,and they are now a big family including large variety of compositions and architectures.Due to large surface area,high pore volume,tunable pore size,and unique mesostructures,mesoporous nanomaterials have been widely used in catalysis,energy conversion and storage,drug delivery,etc.Out of the various methods of architecting mesoporous materials,the soft-templating method that allows regulating the architecture by tuning the assembly process,is used mostly for fabricating mesoporous materials.In soft templating methods,amphiphilic surfactants and precursors assemble into“soft”micelles,and micelles further assemble into mesoporous materials.Usually,micelles homogeneously nucleate and assemble into mesoporous nanomaterials.Such a homogeneous assembly process naturally leads to“routine”structures such as nanospheres or other symmetric architectures.Introduction of nanoparticles during the micelle assembly process results in conventional core@shell structures,which though combining the mesoporous shell and functional core,is still simple.Nowadays,growing demands in diverse applications urgently require mesoporous nanomaterials with novelty in mesostructures,compositions,surface properties,morphologies,functionalities,etc.Therefore,researchers have been seeking to gain better control of the micelles’assembly process,pursuing the synthesis of mesoporous nanomaterials with unique architectures,especially morphology,mesostructure,surface chemistry,etc.Recently,the effect of“interface”during micelles’assembly process has aroused great attention.The introduction of an interface into the reaction system turns the micelles’homogeneous assembly into a heterogeneous one,altering their assembly behavior and thus leading to mesoporous nanomaterials with unique architectures.By manipulation of the interfacial-assembly behavior of micelles,a series of mesoporous nanomaterials with unique architectures have been developed,with structures ranging from symmetric to asymmetric.In this Account,the recent progresses in interfacial-assembly-directed mesoporous nanomaterials with unique architectures,both the fabrication and applications are systematic reviewed.The architectures of the obtained mesoporous nanomaterials are categorized into symmetric and asymmetric,including virus-like,bouquet-like,multishell hollow structures,and also Janus,multipods,hemisphere structures,etc.We introduced how interfaces such as nanoparticle−surface,water−oil interface,macropore scaffold interfaces,etc.are utilized to direct the assembly of micelles.The methods of controlling micelles’interfacial-assembly behavior,such as biphasic assembly method,interfacial-energy method,interface tension method,and so on are highlighted.The applications of these unique mesoporous nanomaterials in fields of catalysis,energy conversion,and biomedicine are surveyed.At the end of the review,a brief summary of the field,as well as shortcomings,challenges,and perspectives of the field are also included. | Tiancong Zhao Liang Chen Runfeng Lin Pengfei Zhang Kun Lan Wei Zhang Xiaomin Li Dongyuan Zhao | 2020 | Accounts of Materials Research2020，1，1： | 1 |

| 8 | Solution-processed multi-resonance organic light-emitting diodes with high efficiency and narrowband emission显示文摘With excellent color purity(full-width half maximum(FWHM)<40 nm)and high quantum yield,multiresonance(MR)molecules can harvest both singlet and triplet excitons for highly efficient narrowband organic light-emitting diodes(OLEDs)owing to their thermally activated delayed fluorescence(TADF)nature.However,the highly rigid molecular skeleton with the oppositely positioned bo ron and nitrogen in generating MR effects results in the intrinsic difficulties in the solution-processing of MR-OLEDs.Here,we demonstrate a facile strategy to increase the solubility,enhance the efficiencies and modulate emission color of MR-TADF molecules by extending aromatic rings and introducing tert-butyls into the MR backbone.Two MR-TADF emitters with smaller singlet-triplet splitting energies(ΔE~(ST))and larger oscillator strengths were prepared conveniently,and the solution-processed MR-OLEDs were fabricated for the first time,exhibiting efficient bluish-green electroluminescence with narrow FWHM of 32 nm and external quantum efficiency of 16.3%,which are even comparable to the state-of-the-art performances of the vacuum-evaporated devices.These results prove the feasibility of designing efficient solutionprocessible MR molecules,offering important clues in developing high-performance solution-processed MR-OLEDs with high efficiency and color purity. | Shen Xu Qingqing Yang Ying Zhang Hui Li Qin Xue Guohua Xie Minzhao Gu Jibiao Jin Ling Huang Runfeng Chen | 2021 | Chinese Chemical Letters2021，32，4： | 1 |

| 12 | Accelerated prediction of Cu-based single-atom alloy catalysts for CO_(2) reduction by machine learning显示文摘Various strategies,including controls of morphology,oxidation state,defect,and doping,have been developed to improve the performance of Cu-based catalysts for CO_(2) reduction reaction(CO_(2)RR),generating a large amount of data.However,a unified understanding of underlying mechanism for further optimization is still lacking.In this work,combining first-principles calculations and machine learning(ML)techniques,we elucidate critical factors influencing the catalytic properties,taking Cu-based single atom alloys(SAAs)as examples.Our method relies on high-throughput calculations of 2669 CO adsorption configurations on 43 types of Cu-based SAAs with various surfaces.Extensive ML analyses reveal that low generalized coordination numbers and valence electron number are key features to determine catalytic performance.Applying our ML model with cross-group learning scheme,we demonstrate the model generalizes well between Cu-based SAAs with different alloying elements.Further,electronic structure calculations suggest surface negative center could enhance CO adsorption by back donating electrons to antibonding orbitals of CO.Finally,several SAAs,including PCu,AgCu,GaCu,ZnCu,SnCu,GeCu,InCu,and SiCu,are identified as promising CO_(2)RR catalysts.Our work provides a paradigm for the rational design and fast screening of SAAs for various electrocatalytic reactions. | Dashuai Wang Runfeng Cao Shaogang Hao Chen Liang Guangyong Chen Pengfei Chen Yang Li Xiaolong Zou | 2023 | Green Energy & Environment2023，8，3： | 0 |
| 13 | Resonance hosts for high efficiency solution-processed blue and white electrophosphorescent devices显示文摘The exploration of high-performance solution-processible host materials for blue and white electrophosphorescent devices is a key and fundamental challenge in the ongoing development of organic semiconductors.Herein,two solution-processible resonance host materials with self-adaptive characteristics are delicately designed and constructed.Because of the dynamic tautomerization upon resonance variation,these smart hosts show self-adaptive and selectively enhanced charge carrier flux at high triplet energy levels.Conferred by the resonance molecules,solution-processed blue and white devices exhibit excellent maximum current efficiencies(CEs)of 29.8 and 57.3 cd A−1,and external quantum efficiencies(EQEs)up to 14.5%and 23.5%,respectively.Our works highlight the significant progress of the solution-processed phosphorescent organic light-emitting diodes(PhOLEDs)using resonance host molecules,potentially furnishing a leap forward in constructing advanced organic semiconductors for next-generation optoelectronic devices. | Huanhuan Li Jibiao Jin Yuan Xiang Ying Zhang Ye Tao Mingguang Li Qin Xue Guohua Xie Wei Huang Runfeng Chen | 2020 | Science China Chemistry2020，63，11： | 0 |
| 14 | Early-Life Gut Microbiota Governs Susceptibility to Colitis via Microbial-Derived Ether Lipids显示文摘Localized intestine inflammation could induce short-term increases in colonic oxygenation and leads to increases in the aerobic bacteria population and reduction in the anaerobic bacteria population by changing the intestinal environment.However,the mechanisms involved and the associated functions of intestinal anaerobes in gut health still remain unclear.Here,we found that early-life depletion of gut microbiota exacerbated later colitis,while mid-life microbiota depletion showed partially reduced colitis.Notably,we observed that early-life gut microbiota depletion confers susceptibility to ferroptosis in colitis.In contrast,restitution of early-life microbiota conferred protection against colitis and inhibited ferroptosis triggered by gut microbiota dysbiosis.Similarly,colonization with anaerobic microbiota from young mice suppressed colitis.These results may attribute to high abundance of plasmalogen-positive(plasmalogen synthase[PlsA/R]-positive)anaerobes and plasmalogens(one of the common ether lipids)in young mice but reduced abundance in the development of inflammatory bowel disease.Early-life anaerobic bacteria elimination also resulted in the aggravation of colitis,while this aggravation phenotype was reverted by plasmalogen administration.Interestingly,plasmalogens inhibited ferroptosis triggered by microbiota dysbiosis.We further find that the alkenyl-ether group of plasmalogens was critical to colitis prevention and ferroptosis inhibition.These data point to one of the mechanisms by which the gut microbiota controls susceptibility to colitis and ferroptosis early in life via microbial-derived ether lipids. | Yanjun Liu Chunhua Jiao Tao Zhang Xue Li Panpan Li Meishan Lu Zhan Ye Yanpeng Du Runfeng Du Wenlong Zhang Jie Xu Zhaojun Zheng Yongjiang Xu Changhu Xue Yi Zhang Yuanfa Liu | 2023 | Research2023，，3： | 0 |

| 16 | Air Stable Chalcogen-Doped Rubicenes with Diradical Character显示文摘Air stable diradicaloid polycyclic aromatic hydrocarbon(PAH)materials possess unique electronic and magnetic properties for various applications.In general,long conjugated distances between two radical centers are required to improve the air stability,thereby complicating the synthetic procedures.Herein,the chalcogen containing rubicenes(O-,S-,and Se-rubicenes)were systematically investigated to understand the chalcogen effects on chalcogen-rubicene physicochemical properties.Impressively,these rubicenes presented unprecedented diradical characterwithin one simple benzene ring and excellent air stabilities.Theirdiradicalcharacterweremanifested by single-crystal X-ray studies,variable-temperature nuclear magnetic resonance,and electron spin resonance.Furthermore,the nucleus independent chemical shifts andthe anisotropy of the induced currentdensity calculations revealed that the formation of diradical was caused by a pro-aromaticity driving force.Importantly,the diradical character of rubicenes are visualizedbyFractionalOccupationNumberWeighted Electron Density(FOD)plots,which present high NFOD values from 1.651 to 1.830.This contribution provided distinctive insights into the structure and property relationship of PAH diradicals. | Liangzhuo Ma Song Wang Yuan Li Qinqin Shi Wenbin Xie Hao Chen Xin Wang Weiya Zhu Lang Jiang Runfeng Chen Qian Peng Hui Huang | 2022 | CCS Chemistry2022，4，12： | 0 |
