Crystal structure of a two-dimensional Cd(Ⅱ)complex and its fluorescence recognition of p-nitrophenol,tetracycline,2,6-dichloro-4-nitroaniline
A Cd(Ⅱ)complex,formulated as {(H2dbim)0.5[Cd(Hbptc)]·H2O}n(1),where dbim=1-(4-((2,6-dimethyl-2H-benzo[d]imidazol-3(3H)-yl)methyl)benzyl)-2,7-dihydro-2,5-dimethyl-1H-benzo[d]imidazole,H4bptc=3,3',4,4'-benzo-phenone tetracarboxylic acid,has been obtained by hydrothermal reactions and structurally characterized.Complex 1 exhibits a 2D layer with a point symbol of {44·66}.Complex 1 was used for fluorescence identification of some com-mon environmental pollutants.The result of the research shows that complex 1 can effectively detect p-nitrophenol,tetracycline,and 2,6-dichloro-4-nitroaniline.The calculated quenching constants for p-nitrophenol,tetracycline,and 2,6-dichloro-4-nitroaniline were 2×102,5.4×104,and 2×104 L·mol-1,respectively.CCDC:1874531.
