The 3D and 2D cadmium coordination polymers as luminescent sensors for detection of nitroaromatics

Two coordination polymers {[Cd2(obtz)(Meip)2]
- H2O}n (1) and {[Cd(obtz)(ndc)]
- 0.5H2O}n (2) were synthesized and characterized. 1 shows a (4,5)-connected 3D network with the point symbol of (44.62)(44.64.82). 2 exhibits a (3,4)-connected 2D network with the point symbol of (3·82)(32.4·82.9). The luminescent properties of 1 and 2 dispersed in various kinds of solvents were investigated in detail. 1 and 2 display highly sensitivity in the detection of nitroaromatics, especially for p-nitrophenol and p-nitroaniline.302
