| 1 | Polymer solar cells with an inverted device configuration using polyhedral oligomeric silsesquioxane-[60]fullerene dyad as a novel electron acceptor显示文摘A polyhedral oligomeric silsesquioxane-[60]fullerene (POSS-C60) dyad was designed and used as a novel electron acceptor for bulk heterojunction (BHJ) polymer solar cells (PSCs) with an inverted device configuration. The studies of time-resolved photoinduced absorption of the pristine thin film of poly[(4,4'-bis(2-ethylhexyl)dithieno[3,2-b:2',3'-d]silole)-2,6-diyl-alt-(4,7-bis (2-thienyl)-2,1,3-benzothiadiazole)-5,5'-diyl] (SiPCPDTBT) and the composite thin film of SiPCPDTBT:POSS-C60 indicated efficient electron transfer from SiPCPDTBT to POSS-C60 with inhibited back-transfer. BHJ PSCs made by SiPCPDTBT mixed with POSS-C60 yielded the power conversion efficiencies (PCEs) of 1.50%. Under the same operational conditions, PCEs observed from BHJ PSCs made by SiPCPDTBT mixed with [6,6]-phenyl-C61-butyric acid methyl ester were 0.92%. These results demonstrated that POSS-C60 is a potentially good electron acceptor for inverted BHJ PSCs. | ZHANG Wen-Bin TU YingFeng SUN Hao-Jan YUE Kan GONG Xiong CHENG Stephen Z.

| 3 | Synthesis and ordered aggregation in water of a blue light-emitting PEO-PHP-PEO triblock oligomer显示文摘A novel blue light-emitting coil-rod-coil triblock oligomer, PEO-PHP-PEO, which consists of para-hexaphenyl (PHP) as the rigid rod and poly(ethylene oxide) (PEO, M w = 750) as the flexible coil, has been synthesized. It is the first soluble poly(para-phenylene) molecule containing no lateral substituent, which can dissolve not only in organic solvents such as chloroform and THF, but also in water. The critical micelle concentration (CMC) of PEO-PHP-PEO in water is 5.25×10-4 mol·L-1 and the surface tension at CMC, 鉉MC, is 61.29 mN·m-1. The absorption peak of the molecularly dissolved PEO-PHP-PEO in water is centered at 323 nm and the fluorescence spectrum has a maximum at 432 nm and shows the vibronic fine structure typical of molecular dissolution. The photoluminescence spectrum of the aggregate solution is similar to that of the PHP polycrystal film, indicating that the ordered packing of PHP block has taken place due to a combination of hydrophobic interaction and p-p stacking. The oligomer self-assembles into cotton-like nanofibers with diameter of about 20 nm in 5.0×10-3 mol·L-1 aqueous solution. | HE Haifeng, CAO Hongqing, WAN Xinhua, TU Yingfeng, CHEN Xiaofang & ZHOU Qifeng Department of Polymer Science and Engineering, College of Chemistry and Molecular Engineering, Peking University, Beijing 100871, China Correspondence should be addressed to Wan Xinhua (e-mail: xhwan@pku.edu.cn) | 2003 | Chinese Science Bulletin2003，48，15： | 2 |

| 9 | Medical micro-and nanomotors in the body显示文摘Attributed to the miniaturized body size and active mobility,micro-and nanomotors(MNMs)have demonstrated tremendous potential for medical applications.However,from bench to bedside,massive efforts are needed to address critical issues,such as cost-effective fabrication,on-demand integration of multiple functions,biocompatibility,biodegradability,controlled propulsion and in vivo navigation.Herein,we summarize the advances of biomedical MNMs reported in the past two decades,with particular emphasis on the design,fabrication,propulsion,navigation,and the abilities of biological barriers penetration,biosensing,diagnosis,minimally invasive surgery and targeted cargo delivery.Future perspectives and challenges are discussed as well.This review can lay the foundation for the future direction of medical MNMs,pushing one step forward on the road to achieving practical theranostics using MNMs. | Huaan Li Fei Peng Xiaohui Yan Chun Mao Xing Ma Daniela A.Wilson Qiang He Yingfeng Tu | 2023 | Acta Pharmaceutica Sinica B2023，13，2： | 0 |
| 10 | PET probes beyond ^(18)F-FDG显示文摘During the past several decades,positron emission tomography(PET) has been one of the rapidly growing areas of medical imaging;particularly,its applications in routine oncological practice have been widely recognized.At present,^(18)F-fluorodeoxyglucose(^(18)F-FDG) is the most broadly used PET probe.However,^(18)F-FDG also suffers many limitations.Thus,scientists and clinicians are greatly interested in exploring and developing new PET imaging probes with high affinity and specificity.In this review,we briefly summarize the representative PET probes beyond ^(18)F-FDG that are available for patients imaging in three major clinical areas(oncology,neurology and cardiology),and we also discuss the feasibility and trends in developing new PET probes for personalized medicine. | Lei Jiang Yingfeng Tu Hongcheng Shi Zhen Cheng | 2014 | The Journal of Biomedical Research2014，28，6： | 0 |
| 11 | Miro2 supplies a platform for Parkin translocation to damaged mitochondria显示文摘PINK1/Parkin-mediated mitophagy is an important process in selective removal of damaged mitochondria, in which translocation of Parkin to damaged mitochondria is recognized as an initiation step. At present, how the damaged mitochondria are selectively recognized and targeted by Parkin is not fully understood. Here we show that Miro2, an outer mitochondrial membrane protein, undergoes demultimerization from a tetramer to a monomer and alteration in mitochondrial localization upon CCCP treatment, suggesting a CCCP-induced realignment of Miro2. The realignment of Miro2 is tightly regulated by PINK1-mediated phosphorylation at Ser325/Ser430 and by Ca^2+binding to EF2 domain, which are both essential for the subsequent Parkin translocation. Interestingly, ablation of Miro2 in mouse causes delayed reticulocyte maturation, lactic acidosis and cardiac disorders. Furthermore, several Miro2 mutations found in the congenital lactic acidosis patients also disable its realignment and Parkin translocation. These findings reveal an important role of Miro2 to mediate Parkin translocation by sensing both depolarization and Ca^2+release from damaged mitochondria to ensure the accuracy of mitophagy. | Jiu-Qiang Wang Shu Zhu Yihan Wang Fengli Wang Chaoqiang An Dongfang Jiang Lijie Gao Yingfeng Tu Xuefei Zhu Yun Wang Hongmei Liu Juanjuan Gong Zhongshuai Sun Xi Wang Leimei Liu Keyan Yang Caixia Guo Tie-Shan Tang | 2019 | Science Bulletin2019，64，11： | 0 |
| 12 | Bladder microenvironment actuated proteomotors with ammonia amplification for enhanced cancer treatment显示文摘Enzyme-driven micro/nanomotors consuming in situ chemical fuels have attracted lots of attention for biomedical applications.However,motor systems composed by organism-derived organics that maximize the therapeutic efficacy of enzymatic products remain challenging.Herein,swimming proteomotors based on biocompatible urease and human serum albumin are constructed for enhanced antitumor therapy via active motion and ammonia amplification.By decomposing urea into carbon dioxide and ammonia,the designed proteomotors are endowed with self-propulsive capability,which leads to improved internalization and enhanced penetration in vitro.As a glutamine synthetase inhibitor,the loaded L-methionine sulfoximine further prevents the conversion of toxic ammonia into non-toxic glutamine in both tumor and stromal cells,resulting in local ammonia amplification.After intravesical instillation,the proteomotors achieve longer bladder retention and thus significantly inhibit the growth of orthotopic bladder tumor in vivo without adverse effects.We envision that the as-developed swimming proteomotors with amplification of the product toxicity may be a potential platform for active cancer treatment. | Hao Tian Juanfeng Ou Yong Wang Jia Sun Junbin Gao Yicheng Ye Ruotian Zhang Bin Chen Fei Wang Weichang Huang Huaan Li Lu Liu Chuxiao Shao Zhili Xu Fei Peng Yingfeng Tu | 2023 | Acta Pharmaceutica Sinica B2023，13，9： | 0 |
| 13 | Janus Polymerization:A One-Shot Approach towards Amphiphilic Multiblock Poly(ester-acetal)s Directly from 1,3-Dioxolane withε-Caprolactone显示文摘Janus polymerization consists of anionic and cationic ring opening polymerizations(AROP and CROP)at the two ends of a single propagating polymer chain,followed by a self-triggered chain extension generating multiblock copolymers(MBCPs)in one step.In the contribution,Janus polymerization by Tm(OTf)_(3) or Er(OTf)_(3) catalyst with an epoxy initiator is applied to synthesize MBCPs of semi-crystalline poly(ε-caprolactone)(PCL)blocks from coordinated AROP and poly(1,3-dioxolane-co-ε-caprolactone)(P(DO-co-CL))blocks from CROP of DO with CL.Meanwhile,amorphous random copolymers[P(DO-r-CL)]are synthesized as control by employing other rare earth triflates[RE(OTf)_(3),RE=Y,Nd,Gd and Lu]as catalysts or in the absence of an initiator via CROP.On account of the distinguishable chemical structures and thermal properties between Janus MBCPs and cationic random copolymers,Janus features are confirmed including the CROP and AROP at a single propagating chain.The resultant amphiphilic copolymers self-assemble to nanoparticles in aqueous solution with designable diameters with the corresponding ratios of hydrophilic and hydrophobic seg-ments.MBCPs exhibit good shape memory properties with appropriate deformation temperature close to human body's,providing a prospect on the applications in biomedical devices. | Huan Qiu Ting Shen Zhening Yang Feng Wu Xiaohong Li Yingfeng Tu Jun Ling | 2022 | Chinese Journal of Chemistry2022，40，6： | 0 |
