Structure and performances of three metal coordination polymers synthesized from 4,4′- (phenylazanediy1) dibenzoic acid

Abstract

Three novel 3D coordination polymers (CPs), [Cd(L)(bifu)]n (1) and [Zn(L)(bimb)0.5]n (2) {[Ni(L)(bifu)](H2O)4}n(3) (H2L = 4,4′-(phenylazanediy1)dibenzoic acid, bifu = 2,7-bis(1-imidazoly)fluorene, bimb = 1,4-bis(imidazol-l-yl)), were obtained under different solvents. Three crystals were also evaluated by elemental analysis, PXRD, single-crystal X-ray diffraction, TGA and FTIR. The result indicated that 3D network structures 1 crystallized in a monoclinic space group P21/n, 2 crystallized in a Orthorhombic space group Pbca and 3 crystallized in a Triclinic space group P-1. Significantly, the dyes adsorption part showed 1 had the necessary ability to adsorb organic dyes methyl orange (MO) and fluorescein sodium (FS). Furthermore, the electrochemical analyses of 3 was also studied.
