Zhicheng Hu, Lei Ying, Fei Huang (黄飞)*, Yong Cao
Sci. China Chem. 2017, 60(5), 571-582
In this mini review, we summarized the recent progress of highly efficient polymer solar cells, with specifical concern on successful strategies of rational molecular design of electron-donating and electron-accepting materials, elaborative interfacial engineering, and reasonable device architectures.
One-pot synthesis of graphene oxide and Ni-Al layered double hydroxides nanocomposites for the efficient removal of U(VI) from wastewater
Shujun Yu, Jian Wang, Shuang Song, Kunyu Sun, Jun Li, Xiangxue Wang, Zhongshan Chen, Xiangke Wang (王祥科)*
Sci. China Chem. 2017, 60(3), 415-422
Herein, we synthesized graphene oxide and Ni-Al LDH (GO@LDH) nanocomposites through a single one-step hydrothermal process, and applied these materials as adsorbents for removing U(VI) from aqueous solutions.
Conjugated polymers containing B←N unit as electron acceptors for all-polymer solar cells
Chuandong Dou (窦传冬)*, Jun Liu (刘俊)*, Lixiang Wang
Sci. China Chem. 2017, 60(4), 450-459
In this review, we focused on introducing the principle of boron-nitrogen coordination bond (B←N), and summarizing our recent research on polymer electron acceptors containing B←N unit for efficient all-PSC devices.
Single-molecule analysis in an electrochemical confined space
Yi-Lun Ying, Yi-Tao Long (龙亿涛)*
Sci. China Chem. 2017, 60(9), 1187-1190
Here, we demonstrate that the electrochemical confined space could efficiently convert single molecule characteristics into measurable electrochemical signatures with high temporal resolution. The human telomere repeat sequence T8 was used as a probe to determine the electrochemical confined effect in a nanopore. Our results show that the nanopore with comparable confined space of the telomere repeat sequence exhibits the most distinguishable single-molecule signals which suggest the folded conformation of T8.
Recent advances in the preparation of Fmoc-SPPS-based peptide thioester and its surrogates for NCL-type reactions
Hongxing Li, Suwei Dong (董甦伟)*
Sci. China Chem. 2017, 60(2), 201-213
This review briefly summarizes recent advances in the engineering and modification of Fmoc-SPPS-derived peptides, which can be used as the N-terminal fragments in a native chemical ligation (NCL) or NCL-type ligation reactions.
120 mm single-crystalline perovskite and wafers: towards viable applications
Yucheng Liu, Xiaodong Ren, Jing Zhang, Zhou Yang (杨周)*, Dong Yang, Fengyang Yu, Jiankun Sun, Changming Zhao, Zhun Yao, Bo Wang, Qingbo Wei, Fengwei Xiao, Haibo Fan, Hao Deng, Liangping Deng, Shengzhong (Frank) Liu (刘生忠)*
Sci. China Chem. 2017, 60(10), 1367-1376
Here we report a method to grow large single-crystalline perovskites including single-halide crystals: CH3NH3PbX3 (X=I, Br, Cl), and dual-halide ones: CH3NH3Pb(ClxBr1−x)3 and CH3NH3Pb(BrxI1−x)3, with the largest crystal being 120 mm in length. Meanwhile, we have advanced a process to slice the large perovskite crystals into thin wafers.
Ni-mediated C–N activation of amides and derived catalytic transformations
Yuan Gao, Chong-Lei Ji, Xin Hong (洪鑫)*
Sci. China Chem. 2017, 60(11), 1413-1424
Focusing on the catalytic transformation, this review summarizes and categorizes the recent advances on the synthetic applications of Ni-mediated C–N bond activation of amides.
Recent advances in radical-mediated fluorination through C–H and C–C bond cleavage
Hong Yan, Chen Zhu (朱晨) *
Sci. China Chem. 2017, 60(2), 214-222
Herein, we summarize the recent advances in radical-mediated C–H and C–C bond fluorination. Three types of transformations are discussed: (1) direct C–H abstraction/fluorination of alkanes; (2) decarboxylative fluorination of alkylcarboxylic acids; (3) ring-opening fluorination.
