Abstract:

Three coordination complexes, {[Cd(HL)(bpea)·H2O]·H2O·DMF}n(1), {[Cd(HL)(bpp)·H2O]·2H2O·DMF}n(2) and {[Cd(HL)(dmbpy)]·DMF}n(3), were obtained from the reaction of 5-(3-carboxy-4-methoxybenzylamino) isophthalic acid(H3L) with cadmium nitrate and different nitrogen-containing ligands under solvothermal conditions, and show interesting 2D→2D penetrating and 1D ribbon structures, respectively. The results reveal that these complexes all demonstrate luminescence quenching effect toward Cr2O72?, while only complex 1 shows a significant fluorescence enhancement in DMF solution of acetylacetone. The flexibility of carboxylate ligand and types and structures of nitrogen-containing ligands play an important role in regulating the structures and fluorescence properties of complexes.
