摘要: Based on a new biscarboxyl-functionalized Schiff base ligand 1,2-cyclohexanediamino-N,N'-bis[3-methoxyl-5-(p-carboxyl-phenylazo)] salicylidene(H4L), four polymers,[(CH3)2NH2]2·[Mn3(L)2(H2O)4]·2DMF(CP1),[Fe2(L)(H2O)(DMF)](CP2),[(CH3)2NH2]·[Cu(HL)]·H2O(CP3) and[Ni2(L)(teta)]·2DMF·H2O(CP4), have been synthesized(teta=5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane). In CP1, both of the internal[N2O2] pocket and the external carboxylate groups of L4- anion are ligated by Mn2+ ions, and the structure displays a layer. In CP2, the Fe2+ cations are linked by L4- anions to form a binuclear double chain. CP3 displays a[Cu2(HL)2] dimer. In CP4, the Ni2+ ions are connected by L4- anions to form a chain. The structures are further linked by hydrogen bonds to form 2D or 3D supramolecular architectures, respectively. CP1 exhibits adsorption ability to three organic dyes.
