4Unraveling Passivation Mechanism of Imidazolium-Based Ionic Liquids on Inorganic Perovskite to Achieve Near-Record-Efficiency CsPbI_(2)Br Solar Cells显示文摘The application of ionic liquids in perovskite has attracted wide-spread attention for its astounding performance improvement of perovskite solar cells(PSCs).However,the detailed mechanisms behind the improvement remain mysterious.Herein,a series of imidazolium-based ionic liquids(IILs)with different cations and anions is systematically investigated to elucidate the passivation mechanism of IILs on inorganic perovskites.It is found that IILs display the following advantages:(1)They form ionic bonds with Cs^(+)and Pb^(2+)cations on the surface and at the grain boundaries of perovskite films,which could effectively heal/reduce the Cs^(+)/I−vacancies and Pb-related defects;(2)They serve as a bridge between the perovskite and the hole-transport-layer for effective charge extraction and transfer;and(3)They increase the hydrophobicity of the perovskite surface to further improve the stability of the CsPbI_(2)Br PSCs.The combination of the above effects results in suppressed non-radiative recombination loss in CsPbI_(2)Br PSCs and an impressive power conversion efficiency of 17.02%.Additionally,the CsPbI_(2)Br PSCs with IILs surface modification exhibited improved ambient and light illumination stability.Our results provide guidance for an indepth understanding of the passivation mechanism of IILs in inorganic perovskites.Jie Xu Jian Cui Shaomin Yang Yu Han Xi Guo Yuhang Che Dongfang Xu Chenyang Duan Wenjing Zhao Kunpeng Guo Wanli Ma Baomin Xu Jianxi Yao Zhike Liu Shengzhong Liu 2022Nano-Micro Letters2022,14,1:1

18Prebiotic Chemistry in Aqueous Environment:A Review of Peptide Synthesis and Its Relationship with Genetic Code显示文摘Prebiotic peptide synthesis and the origin of the genetic code are central issues concerning the origin of life.The question of how they are possibly correlated on the primordial Earth remains perplexing,although numerous experiments have been carried out to explain the prebiotic chemistry of peptide synthesis and the genetic code origin.The purpose of this article is to review the chemical reactions occurred during the synthesis of peptides and the origin of the genetic code in the early Earth aqueous environment.Meanwhile,we attempt to review their relationship as well.At last,from our perspective,the chiral properties of biomolecules should be taken into account in the prebiotic chemical scenarios,which may contribute to some breakthroughs in the further research of this field.Jianxi Ying Ruiwen Ding Yan Liu Yufen Zhao 2021Chinese Journal of Chemistry2021,39,8:0
19Enhancing the Adsorption Capacity of TMA-montmorillonite Toward HOCs显示文摘Organoclays synthesized with small organic cations can effectively adsorb hydrophobic organic compounds (HOCs), and the hydrophobic siloxane surfaces of clay minerals have been considered as the main adsorption sites for HOCs. Therefore, reducing charge density of clay minerals which can effectively increase the exposed siloxane surface areas has been generally used to enhance the adsorption capacity of organoclays towards HOCs. In this work, we will present a new method to increase the exposed siloxane surface areas of the synthesized organoclays and enhance their adsorption capacity. Firstly, the original inorganic cations on montmorillonite were exchanged with Li+, and then part of the Li+ (i.e., 20% to 60% of the montmorillonite’s CEC) were further exchanged with tetramethylammonium cation (TMA). After that ,the samples were heated at 200 ℃ for 12 h to make sure most of the Li+ were transferred to montmorillonite layers. With this method the layer charge of montmorillonite can be effectively reduced while the layered structure of montmorillonite will be preserved by pre-exchanged TMA. Finally, the remaining Li+ cations were further exchanged with TMA. The structural and adsorptive characteristics of the resulting organoclays were compared with those synthesized using traditional method (i.e., first reducing the charge density and then exchanging TMA).ZHU Runliang ZHAO Junbo ZHU Jianxi HE Hongping 2013矿物学报2013,33,S1:0
20Trimetaphosphate-induced chiral selection between amino acid and nucleoside using ^(15)N-^(31)P coupling NMR显示文摘Life on Earth uses a common set of L-amino acids(L-aa)to construct proteins and D-nucleosides(D-Nu)to form nucleic acids,which serve as the carrier of genetic information.Herein,we reveal the in-trinsic mechanism of chiral selection of L-aa and D-Nu from the perspective of chemical origin of life.This work employed^(15)N-labeled L-aa and performed one-pot synthesis of nucleotide amidate of amino acid(N-aa-NMP)using equal amounts of L-^(15)N-aa and D-^(14)N-aa with D-/L-Nu in the aqueous solution of trimetaphosphate,generating L-^(15)N-aa-NMP and D-^(14)N-aa-NMP,respectively.The ^(31)P-NMR data indicated that L-aa was preferentially selected during the formation of N-aa-NMP in the presence of D-Nu.Surpris-ingly,D-aa was preferred over L-aa in the presence of L-Nu.Further analysis revealed that L-^(15)N-aa-D-NMP vs.D-^(14)N-aa-L-NMP and D-^(14)N-aa-D-NMP vs.L-^(15)N-aa-L-NMP were mirror isomers of each other,respec-tively.These data suggest that there could be a set of chiral systems opposite to that on Earth,which infers there might be a world of life that is a mirror image of the Earth.Jianxi Ying Ruiwen Ding Yumeng Zhang Bowen Han Yeting Guo Ning Wang Dandan Guo Yile Wu Junwei Huang Yan Liu Feng Ni Shaohua Huang Yufen Zhao 2022Chinese Chemical Letters2022,33,2:0
