Synthesis of Halide-Modulated Cuprous(I) Coordination Polymers with Mechanochromic and Photocatalytic Properties.

Abstract

Two copper(I) halide-based coordination polymers, namely, [Cu3Cl2(Tipa)2]Cl (1, (Tipa = tris(4-(1H-imidazol-1-yl)phenyl)amine) and [Cu3I3(CuI)2(Tipa)3] (2), were obatined under the solvothermal reactions, respectively. Compound 1 with the chain structure shows unique Cu···Cu interactions, C-H···Cl halogen hydrogen bonds, and π···π stacking interactions. It also exhibits unusual mechanochromic and photocatalytic properties on degradation of methylene blue (MB).
