One Cd(II) coordination polymer based on flexible 4,4′-di(4H-1,2,4-triazole-4-yl)methyldiphenyl: Synthesis, structure and luminescent property

Abstract

Under hydrothermal conditions, one Cd(II) coordination polymer (Cd-CP) has been successfully created using the flexible bis-triazole ligand and dicarboxylate ligand. In Cd-CP, one-dimensional chain structure is created by the interconnection of the adjacent cadmium ions via water bridges. To create a two-dimensional layer structure, the mutually parallel one-dimensional cadmium chains are connected further by dicarboxylate ligands. The final three-dimensional stacking structure is formed by bis-triazole ligands connecting adjacent two-dimensional layers. The theoretical computations and the experimental fluorescence characteristics are in agreement, which shed deep light on the fluorescence properties of Cd-CP. The associated findings demonstrate that the carboxylate and bis-triazole coligands can successfully modify the architectures of coordination polymers, which illustrates the feasibility of constructing functional coordination materials from bis-triazole ligands.
