摘要
将柔性苄氨基三羧酸配体5-(3-羧基-4-甲氧基苄氨基)间苯二甲酸(H3L)与硝酸镉和不同含氮配体在溶剂热条件下反应,制得了配合物{[Cd(HL)(bpea)·H2O]·H2O·DMF}n(1)、{[Cd(HL)(bpp)·H2O]·2H2O·DMF}n(2)和{[Cd(HL)(dmbpy)]·DMF}n(3)[bpea=bis(4-pyridyl)ethane;bpp=1,3-bis(4-pyridyl)propane;dmbpy=5,5′-dimethyl-2,2′-bipyridine].3个配合物分别表现出有趣的2D→2D穿插结构和一维带状结构.荧光性质测试结果表明,所有配合物的荧光均可被Cr2O72‒猝灭,而在乙酰丙酮的DMF溶液中,只有配合物1表现出明显的荧光增强.羧酸配体的柔性、含氮配体的类型和结构可以调控配合物的结构和荧光性能.
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-car⁃boxy-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,re⁃spectively.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.
