Abstract

Graphical abstract: Two new Cd(II) coordination polymers (CPs) were synthesized under hydrothermal condition, CPs1 –2 exhibitsql topology. Abstract: Two new Cd(II) supramolecular coordination polymers (CPs) formulated as [Cd(L1)(DCTP)] n (1 ) and {[Cd(L2)(HBTC)(H2 O)]·H2 O} n (2 ) [H2 DCTP = 2, 5-dichloroterephthalic acid, H3 BTC = 1, 3, 5-benzenetricarboxylic acid, L1 = 1, 3-bis(2-methylbenzimidazol-1-ylmethyl)benzene and L2 = 1, 2-bis(imidazol-1-ylmethyl)benzene] were hydrothermally synthesized. Both CPs exhibit 2D (4, 4) layered structures and further extend into 3D supramolecular frameworks by π – π stacking interactions for CP1, OH⋯O classic hydrogen bonding interactions for CP2, respectively. The luminescence and photocatalytic properties of CPs1 –2 for the degradation of methylene blue also presented.
