Toward future commercial applications of organic solar cells(OSCs),organic photovoltaic materials that enable high efficiency,excellent stability,and low cost should be developed.Fused-ring electron acceptors(FREAs)have declared that OSCs are capable of showing efficiencies over 19%,whereas stability and cost are not solved yet.As the counterparts of FREAs,non-fused ring electron acceptors(NFREAs)are more flexible in molecular design.They have better stability because of the reduction of intramolecular tension via breaking fused backbone and have more advantages in cost with the reduction of synthetic complexity.However,the challenge for NFREAs is the relatively lower efficiencies(around 15%at current stage),which require better molecular designs for addressing the issues of conformational unicity and effective molecular packing.In this Account,we comprehensively summarize works about NFREAs carried out in our group from three main frameworks,including molecular design and efficiency optimization,material cost,and stability.First,in the part of molecular design and efficiency optimization,the existing rotatable single bond in NFREAs will bring the problem of conformational uncertainty,but it can be solved through proper molecular design,which also regulates the energy levels,light absorption range,and the packing mode of the molecule for obtaining higher performance.Thus,in this part,we discuss the evolution of NFREAs in three aspects,including molecular skeleton optimization,terminal modification,and side chain engineering.Many strategies are used in the design of a molecular skeleton,such as utilizing the quinoid effect,introducing functional groups with the electron push−pulling effect,and using multiple conformational lock.Furthermore,simplifying the skeleton is also the preferred development tendency.As for the terminal,the main modification strategy is adjusting the conjugation length and halogen atoms.What is more,by adjusting the side chain to induce appropriate steric hindrance,we can fix the orientation

The hydrogen peroxide(H2O2)catalyzed by nanoparticles(NPs)demonstrates potential broad applications in the field of biomedicine and environmental protection.However,a systematic understanding of the catalytic mechanism severely limited the rational design of NPs with better enzyme-like activity and selectivity.Here,compared with the widely concerned Fe3O4NPs,the decomposition process of H_(2)O_(2) on reductive Co P NPs and p H-regulated peroxidase-and catalase-like activities with 3,3′,5,5′-tetramethylbenzidine(TMB)as reductive substrates were explored.All results show that OH·radical intermediates generated from the decomposition of H2O2*/OOH*at acidic conditions and complexed with TMB via H-bonds(complexed OH·)are the principal oxidant of TMB rather than free OH·as reported.Besides,the produced O*/OH*on Co P NPs shows negligible oxidation activity due to the strong reducibility of catalysts.The high coverage of O*/OH*from the dissociation of H2O2(H2O)at neutral(alkaline)p H conditions on Co P NPs enhances the dehydrogenation of H_(2)O_(2) to O2,leading to the transition between peroxidase-and catalase-like activities.

Genes & Diseases 2023年第5期10卷 2167-2178页

作者： Junping Liu Yutong shi minmin Wu Fengmei Zhang Mengqi Xu Zhiqiang He Min Tang Key Laboratory of Laboratory Medical Diagnostics Designated by the Chinese Ministry of Education Chongqing Medical UniversityChongqing 400016China

Despite significant improvements in five-year survival rates due to early diagnosis and combination therapy, triple-negative breast cancer (TNBC) treatment remains a major challenge. Finding new and effective targets for diagnosis and drug therapy is urgent for TNBC patients. Jagged-1 (JAG1), one of the canonical ligands of the Notch signaling pathway, is involved in vascular budding and is a poor prognostic factor of TNBC. In this study, combined with quantitative real-time PCR, database analysis, animal experiments, and other means, JAG1 was confirmed to be related to the poor prognosis of TNBC patients. JAG1 was highly expressed in MDA-MB-231 Bone (231B) cells, with stronger invasion and metastasis ability than MDA-MB-231 (231) cells. Treatment of human vascular endothelial cells (HUVEC) with TNBC conditioned medium showed that TNBC JAG1 promoted the angiogenesis of HUVEC. Next, we detected the exosomes extracted from TNBC conditioned medium and found that JAG1 promoted the exosome secretion from 231 cells via ALIX-RAB11A/RAB35. In addition, we also found that the exosomes from JAG1 overexpressed TNBC cells contained more long non-coding RNA (lncRNA) MALAT1 , and MALAT1 promoted angiogenesis of HUVEC by targeting miR-140-5p . Finally, the angiogenesis-promoting effect of JAG1 in TNBC was further investigated by matrix gel assay. In conclusion, we reveal that JAG1 has a pro-invasion effect on TNBC and is involved in microenvironment angiogenesis by promoting exosome secretion and the MALAT1-miR-140-5p-JAG1/VEGFA pathway.

The production and application of organophosphate esters(OPEs)have dramatically increased in recent years due to their use as a replacement for brominated flame retardants.In this study,13 OPEs(∑_(13)OPEs)were analyzed in indoor air samples from kitchens and living rooms in 14 residential homes in Beijing,China.The concentrations of ∑_(13)OPEs in kitchen air samples(mean:13 ng/m^(3))were significantly(p<0.05)higher than in living room air samples(5.0 ng/m^(3)).In addition,paired window surface organic film samples were collected and analyzed to investigate film-air partitioning,exhibiting a mean concentration of ∑_(13)OPEs of 4100 ng/m^(2).The congener profiles showed that tris(2-chloroisopropyl)phosphate(TCPP)was the predominant compound in both window film samples(48%)and the corresponding indoor air sample(56%).The estimated daily intakes(EDI)of OPEs via indoor air inhalation were 2.8 and 1.4 ng/kg/day for infants and adults,respectively,both of which are below the reference dose values(RfDs).Overall,these findings indicate that OPEs in the indoor air environment of residential homes in Beijing are not likely to pose a health risk to the general population.

A non-fullerene acceptor enables efficient P3HT-based organic solar cells with small voltage loss and thickness insensitivity

引用

Chinese Chemical Letters 2019年第6期30卷 1277-1281页

作者： Ning Wang Weitao Yang Shuixing Li Minmin Shi Tsz-Ki Lau Xinhui Lu Rafi shikler Chang-Zhi Li Hongzheng Chen MOE Key Laboratory of Macromolecular Synthesis and Functionalization State Key Laboratory of Silicon Materials Department of Polymer Science and Engineering Zhejiang University Hangzhou 310027 China Department of Physics The Chinese University of Hong Kong Hong Kong 999077 China Department of Electrical and Computer Engineering Ben-Gurion University of the Negev Beer-Sheva 8410501 Israel

Poly(3-hexylthiophene)(P3HT) is a low-cost polymer donor for organic solar cells (OSCs). However, the P3HT-based OSCs usually give low power conversion efficiencies (PCEs) due to the wide bandgap and the high-lying energy levels of P3HT. To solve this problem, in this work, we design and synthesize a new A-D-A type non-fullerene acceptor, DFPCBR, which owns an electron-donating (D) core constructed by linking a 2,5-difluorobenzene ring with two cyclopentadithiophene moieties, and two electron-accepting (A) end-groups of benzo[c][1,2,5]thiadiazole connected with 3-ethyl-2-thioxothiazolidin-4-one. Because of the strong electron-donating ability and large conjugation effect of D core, DFPCBR shows appropriate energy levels and a narrow bandgap matching well with those of P3HT. Therefore, with P3HT as the donor and DFPCBR as the acceptor, the OSCs possess broad absorption range from 350 nm to 780 nm and the reduced energy loss (Eloss) of 0.79 eV (compared with ~1.40 eV for the P3HT:PC61BM device), providing a good PCE of 5.34% with a high open-circuit voltage (VOC) of 0.80 V. Besides, we observe that the photovoltaic performances of these devices are insensitive to the thickness of the active layers:even if the active layer is as thick as 320 nm,~80%of the best PCE is maintained, which is rarely reported for fullerene-free P3HT-based OSCs, suggesting that DFPCBR has the potential application in commercial OSCs in the future.

奥古斯丁常被视为典型的柏拉图主义者,本文则透过考察奥古斯丁的身心观念,论证其哲学观念中“非柏拉图主义”和“超越柏拉图主义”的思想成分。首先,本文论证奥古斯丁并不是一贯地使用柏拉图主义的典型的身体和灵魂的二分法,他还使用体、魂和灵的三分法,随论述需要而取用,既有别于传统柏拉图主义的二分法,也有别于激进柏拉图主义的三分法。其次,本文论证奥古斯丁在体、魂和灵关系的观念上,强调体、魂和灵的统一性,既有别于传统柏拉图主义的灵魂与身体分离的观念,又有别于激进柏拉图主义的体、魂和灵三者完全分离的思想。本文论证了奥古斯丁的身体观念,指出他肯定身体的自然正当性,一反柏拉图主义传统否定身体的做法,推动了现代身体观念的形成。

The ternary strategy for incorporating multiple photon-sensitive components into a single junction has emerged as an effective method for optimizing the nanoscale morphology and improving the device performance of organic solar cells （OSCs）.In this study,efficient and stable ternary OSCs were achieved by introducing the small-molecule dye （5E,5＆#39;E）-5,5＆#39;-（4＆#39;,4″-（1,2-diphenylethene-1,2-diyl）bis（biphenyl-4＆#39;,4-diyl））bis（methan-1-yl-1-ylidene）bis（3-ethyl-2-thioxothia zolidin-4-one）（BTPERn） into poly[4,8-bis（5-（2-ethylhexyl）thiophen-2-yl）benzo[1,2-b：4,5-b＆#39;]dithiopheneco-3-fluorothieno[3,4-b]thiophene-2-carboxylate] （PTB7-Th）：[6,6]-phenyl C71 butyric acid methyl ester （PC71BM） blend films processed using a 1,8-diiodooctane （DIO）-free solvent.The incorporation of BTPE-Rn enhanced the short-circuit current density and fill factor of the ternary OSCs compared with those of binary OSCs.An investigation of the optical,electronic,and morphological properties of the ternary blends indicated that the third component of BTPE-Rn not only promoted the photon utilization of blends through the energy-transfer process but also improved the electron mobility of the blends owing to the fullerene-rich nanophase optimization.More importantly,this ternary strategy of utilizing a small-molecule dye to replace the photounstable DIO additive enhanced the operational stability of the OSCs.
