基于硫修饰芳香羧酸配体的一维Cd配合物:合成、结构及荧光传感性质
1-D Cd Complexes based on Sulfur-decorated Aromatic Carboxylic Acids:Syntheses, Structures and Fluorescence Sensing Properties
摘要
Abstract
Two new one-dimensional complexes, namely, [Cd (L1) (5, 5′-dmbpy) ]n (1), [Cd (L2) (dibp) ]n (2) (H2 L1=2, 2′-[benzene-1, 3-diylbis (methanediylsulfanediyl) ]dibenzoic acid, H2 L2=2, 2'-[benzene-1, 4-diylbis (methanediylsulfanediyl) ]dibenzoic acid, 5, 5′-dmbpy=5, 5′-DiMethyl-2, 2′-dipyridyl, dibp=1, 3-bis[ (1 H-imidazol-1-yl) methyl]benzene), have been solvothermally synthesized and fully characterized.The fluorescence measurements reveal that each complex exhibits selectivity and sensitivity towards Fe3+and Cr2O72- ions in DMF.For complex 1, the binding constants to Fe3+and Cr2O72- ions were 2.72×104 and 3.59×103 M-1, respectively.And the detection limits were 1.34 and 4.90μM, respectively.For complex 2, the binding constants to Fe3+and Cr2O72- ions were 5.23 × 104 and 1.56×103 M-1, respectively.The detection limits were 2.09 and 5.86μM, respectively.Furthermore, the sensing mechanism was investigated and discussed in details.关键词
