Abstract

Assembly of AgS^tBu and PhCOOH ligands with the assistance of soluble silver salt CH₃COOAg/CF₃SO₃Ag in methanol, N, N-dimethylformamide (DMF) and dichloromethane solution, yielded two Ag₂₀ cage isomers co-constructed by thiol and carboxylate/sulfonate ligands encapsulating a CO₃^2– anion template, [(CO₃^2–)@Ag₂₀(S^tBu)₁₀(PhCOO)₄(CH₃COO)₄(DMF)₄] (1) and [(CO₃^2–)@Ag₂₀(S^tBu)₁₀(PhCOO)₆(CF₃SO₃)₂(DMF)₄]·2DMF (2). The CO₃^2– anion template was generated in situ by fixing atmospheric CO₂. The precise structures of 1 and 2 were confirmed by single-crystal X-ray diffractometry (SCXRD). The thermal stability of compounds 1 and 2 was proved by thermogravimetric (TG) analysis, and their solution stability was characterized by nuclear magnetic resonance hydrogen spectroscopy (¹H NMR). The absorption spectra, photocurrent responses, and luminescence of compounds 1 and 2 were investigated. In addition, the photodegradation of methylene blue (MB) and cyclic voltammetry characteristic curves of 1 and 2 were also studied.

硫醇和羧酸盐/磺酸盐共构并由 CO32- 模板诱导的两种 Ag20 笼异构体的光电流、电化学特性和光降解作用

在可溶性银盐 CH3COOAg/CF3SO3Ag 的帮助下，在甲醇、N, N-二甲基甲酰胺（DMF）和二氯甲烷溶液中组装 AgStBu 和 PhCOOH 配体、得到了由硫醇和羧酸盐/磺酸盐配体包裹 CO32- 阴离子模板共同构建的两种 Ag20 笼异构体：[(CO32-)@Ag20(StBu)10(PhCOO)4(CH3COO)4(DMF)4] (1) 和 [(CO32-)@Ag20(StBu)10(PhCOO)6(CF3SO3)2(DMF)4]-2DMF(2)。CO32- 阴离子模板是通过固定大气中的二氧化碳就地生成的。单晶 X 射线衍射仪（SCXRD）证实了 1 和 2 的精确结构。热重（TG）分析证明了化合物 1 和 2 的热稳定性，核磁共振氢谱（1H NMR）鉴定了它们的溶液稳定性。研究了化合物 1 和 2 的吸收光谱、光电流响应和发光。此外，还研究了亚甲基蓝（MB）的光降解以及 1 和 2 的循环伏安特性曲线。
