Carbon-oxygen-bridged (CO-bridged) ladder-type units already proved to be promising electron-donating building blocks for making acceptor-donor-acceptor (A-D-A) nonfullerene acceptors [1].Compared with traditional carbon-bridged (C-bridged) units, CObridged units present stronger electron-donating capability due to electron-rich oxygen atoms.

Organic-inorganic lead halide perovskite solar cells(PSCs)have been marching rapidly in recent years with power conversion efficiency(PCE)boosting from 3.8%to 24.2%(NREL Best Research-Cell Efficiency Chart,https://***/pv/cell-effi ***,Accessed April 2019).However,these solar cells are not stable at high temperatures due to volatile organic cations[1].Allinorganic perovskites with cesium cation like CsPbI1-xBrx present high thermal stabilities[2].By partially replacing I-with Br-,the bandgap for CsPbI1-xBrx can be tuned from 1.73 to 2.36 eV.

A carbon-oxygen-bridged ladder-type building block for efficient donor and acceptor materials used in organic solar cells

引用

Science Bulletin 2017年第19期62卷 1331-1336页

作者： Zuo Xiao Fan Liu Xinjian Geng Jianqi Zhang Shizhe Wang Yujun Xie Zhen Li Huai Yang yongbo yuan Liming Ding Center for Excellence in Nanoscience (CAS) Key Laboratory of Nanosystem and Hierarchical Fabrication (CAS)National Center for Nanoscience and Technology Department of Chemistry Wuhan University College of Engineering Peking University School of Physics & Electronics Central South University

A carbon-oxygen-bridged ladder-type donor unit （CO5） was invented and prepared via an ＂intramolecu- lar demethanolization cyclization＂ approach. Its single crystal structure indicates enhanced planarity compared with the carbon-bridged analogue indacenodithiophene （IDT）. Owing to the stronger electron-donating capability of CO5 than IDT, CO5-based donor and acceptor materials show narrower bandgaps. A donor-acceptor （D-A） copolymer donor （PCO5TPD） and an A-D-A nonfullerene acceptor （COSIC） demonstrated higher performance than IDT-based counterparts, PIDTTPD and IDTIC, respec-tively. The better performance of CO5-based materials results from their stronger light-harvesting capability and higher charge-carrier mobilities.

Synthetic biology is an interdisciplinary field that takes top-down approaches to understand and engineer biological systems through design-build-test cycles. A number of advances in this relatively young field have greatly accelerated such engineering cycles. Specifically, various innovative tools were developed for in silico biosystems design, DNA de novo synthesis and assembly, construct verification, as well as metabolite analysis, which have laid a solid foundation for building biological foundries for rapid prototyping of improved or novel biosystems. This review summarizes the state-of-the-art technologies for synthetic biology and discusses the challenges to establish such biological foundries.
