Abstract

A racemic bis(pyridyl) ligand (L) was synthesized and characterized following our previous work. Subsequently, a series of Ag(I) coordination polymers (CPs) were synthesized from this ligand with silver(I) salts containing nine different anions and further characterized by single-crystal X-ray diffraction analysis. The crystal structures of CPs 1–9 show that the anions play a vital role in the chiral assembly process of L with different silver(I) salts, resulting in homochiral or heterochiral complexes. CPs 1–3 exist as 2D homochiral conglomerates formed by spontaneous chiral resolution. CPs 4–8 exist as 1D heterochiral tube-like chains, and CP 9 adopts a 1D heterochiral zig-zag chain structure. Furthermore, CPs 2, 4, and 9 were chosen as representatives to investigate their photocatalytic performances for the degradation of organic dyes. The results showed that CP 4 is much more active than CPs 2 and 9 for the degradation of both rhodamine B (RhB) and methylene blue (MB) under UV light irradiation, and it is thus inferred that CPs 4–8 are suitable as potential photocatalysts for the degradation of RhB and MB in water. This work has revealed that the chiral assembly structures induced by anions lead to differences in their photocatalytic performances.

阴离子诱导的手性组装:用于光催化降解有机染料的银(i)配位聚合物的构建
在前人的基础上合成了一种外消旋双吡啶基配体(L)。随后,该配体与含有9种不同阴离子的银(I)盐合成了一系列银(I)配位聚合物(CPs),并通过单晶x射线衍射分析对其进行了表征。CPs 1-9的晶体结构表明阴离子在L与不同银(I)盐的手性组装过程中起着至关重要的作用,从而形成同手性或异手性配合物。CPs 1-3以自发手性拆分形成的二维同手性聚合体存在。cp4 - 8为一维异手性管状链,cp9为一维异手性之字形链。此外,以CPs 2、4和9为代表,研究了它们对有机染料的光催化降解性能。结果表明,在紫外光照射下,cp4对罗丹明B (RhB)和亚甲基蓝(MB)的降解活性明显高于cp2和cp9,因此推断cp4 - 8适合作为水中降解RhB和MB的潜在光催化剂。这项工作揭示了阴离子诱导的手性组装结构导致其光催化性能的差异。
