论文摘要:In article number 1903239, Junsheng Yu, Wei Huang, Ziyi Ge, Tobin J. Marks, Antonio Facchetti, and co‐workers present a spontaneous passivation method to greatly improve the performance of perovskite solar cells (PSCs) by using a zwitterionic small‐molecule electrolyte. This bottom‐up passivation is a novel and promising strategy to overcome outstanding issues impeding PSC advances in the future.

论文题目:Harnessing combinational phototherapy via post-synthetic PpIX conjugation on nanoscale metal–organic frameworks

论文作者:Rui Chen, Wen-Cheng Chen, Li Yan, Shuang Tian, Bin Liu, Xianfeng Chen, Chun-Sing Lee, Wenjun Zhang

发表日期:August 21,2019

论文摘要:Nanomaterial-mediated phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), is an effective anticancer intervention that relies on light activation of photoactive nanomaterials localized in tumors. Recently, combinational PDT/PTT offered a practical pathway to relieve resistance of monotherapy, surmount undesirable side effects and provide a synergistic effect to enhance phototherapeutic efficiency. Herein, we report a facile strategy to integrate protoporphyrin IX (PpIX) into nanoscale metal–organic frameworks (NMOFs) and control their photoactive properties for combinational cancer PDT and PTT. With optimized PpIX conjugation, the as-fabricated nanoparticles (nPCU NPs) exhibit (1) improved dispersibility and particle stability, (2) simultaneous generation of reactive oxygen species and heat effectively through activation by a single-wavelength laser of 635 nm, and (3) maintenance of porosity for further application as drug delivery vehicles. Moreover, in vitro investigation of nPCU NPs demonstrates effective cellular uptake, successful endosomal escape and enhanced phototherapeutic efficacy under both normoxic and hypoxic conditions. Therefore, this study developed a novel type of phototherapeutic nanoplatform with optimal properties for applicable cancer phototherapy.

论文题目:Crystallinity and grain boundary control of TIPS-pentacene in organic thin-film transistors for the ultra-high sensitive detection of NO2

论文作者:Bingyao Shao, Yiming Liu, Xinming Zhuang, Sihui Hou, Shijiao Han, Xinge Yu, Junsheng Yu

发表日期:September 07,2019

论文摘要:Herein, ultra-sensitive nitrogen dioxide (NO2) gas sensors based on 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) organic thin-film transistors (OTFTs) are reported. These sensors were fabricated by a simple solvent selection method that enabled crystallinity and grain boundary (GB) control and regulation; superior sensitivity of the sensors could be achieved using appropriate organic solvents to balance the crystallinity and density of the GBs in TIPS-pentacene films. o-Xylene was proved to be the best organic solvent for the optimization of the crystallinity and GB density in TIPS-pentacene films. The sensitivity of the sensors processed using o-xylene towards 10 ppm NO2 was more than 58 times that of the devices processed using the chlorobenzene solvent. Importantly, the limit of detection (LOD) of 1.93 ppb was achieved by our best NO2sensors. A series of characterizations and tests, including morphology, crystal structure, and surface chemical group measurements, were carried out to illustrate the sensing mechanism. Moreover, the real-time sensing, reproducibility, selectivity, and low gate-voltage tests of these devices were conducted, and the results demonstrated that the selection of an appropriate solvent was essential to achieve high-performance gas sensors.

论文题目:Novel blue fluorescent emitters structured by linking triphenylamine and anthracene derivatives for organic light-emitting devices with EQE exceeding 5%

论文作者:Jing Zhang, Yaping Zhao, Huixia Xu, Di Zhang, Yanqin Miao, Ruth Shinar, Joseph Shinar, Hua Wang, Bingshe Xu, Yucheng Wu

发表日期:September 21,2019

论文摘要:Achieving an external quantum efficiency exceeding 5% for traditional blue fluorescent organic light emitting devices (OLEDs) is still a current challenge due to the 25% limit of the radiative exciton yield. Bipolar organic molecules with a special hybrid local-excited and charge-transfer state have showed huge potential to address this issue. Herein, we designed and synthesized two novel bipolar compounds, namely TPA-AN-NA and TPA-AN-TFP, which were structured by simply linking a donor of triphenylamine (TPA) and both acceptors of anthracene derivatives. Both resulting compounds show good blue emission with emission peaks at 468 and 471 nm and photoluminescence quantum yields of 30.68 and 23.96% in thin films for TPA-AN-NA and TPA-AN-TFP, respectively. They also exhibit good solubility and can dissolve in several organic solvents with different polarities. Further, the fabricated blue OLEDs with TPA-AN-NA and TPA-AN-TFP as emitters also realize the corresponding blue emission well with electroluminescence peaks at 464 and 472 nm, respectively. The TPA-AN-NA-based blue device achieves a high external quantum efficiency of 5.44% and a radiative exciton yield of 56.68%, exceeding the theoretical limit.

论文题目:Highly efficient prismatic perovskite solar cells

论文作者:Jiang Huang, Siheng Xiang, Junsheng Yu, Chang-Zhi Li

发表日期:March 01,2019

论文摘要:Lead halide perovskites, such as methylammonium lead iodide (MAPbI3) can reach near 100% internal quantum efficiency in single solar cells, but they still encounter significant thermodynamic losses in photon energy to offset device photovoltage and performance. Herein, a novel prismatic perovskite solar cell with light trapping configuration, namely, Prim PVSC, is designed to mitigate such losses in devices, through modulating the pathway of light inside series cells, wherein incident high-to-low energy photons are separately captured by four horizontally aligned MAPbIxBr3−x subcells with varied bandgaps. This newly designed PVSC has remarkably led to a record open circuit voltage of 5.3 V in four series devices and power conversion efficiency of 21.3%, which could provide a new way to break the performance bottleneck of perovskites. Practically, this type of device architecture could also be applied in flexible modules for large-area application.
