Abstract
A new compound of {[Cu-2(L)(2)(2,2'-bipy)(2)(H2O)(2)]center dot 2H(2)O}(n) (1) (H2L = 1,3-bis(4'-carboxylatophenoxy)benzene, 2,2'-bipy = 2,2'-bipyridine), was prepared and full characterized. 1 shows a metallacycle unit, which was further extended into 3D supramolecular motif through the pi-pi packing and H-bonded interactions. 1 obtained effectively photocatalytic performance to the disintegration of Rhodamine B (Rh B) compared to the dyes of basic green (BG), methyl violet (MV) and methylene blue (MB). In addition, the plausible mechanism displayed by 1 for the catalytic degradation toward Rh B was proposed using the trapping method and LC-MS studies.
