摘要：

A stable two-dimensional (2D) coordination Cd(II) polymer [Cd(ppvppa)(1,4-NDC)](n) (1) (ppvppa = N-(pyridin-2-yl)-N-(4-(2-(pyridin-4-yl)vinyl)phenyl)pyridin-2,amine; 1,4-H(2)NDG = 1,4-naphthalenedicarboxylic acid) was prepared by the solvothermal reactions of-Cd(NO3)(2)center dot 4H(2)O with ppvppa and 1,4-H2NDC in H2O and MeCN at 150 degrees C. Compound 1 was characterized by elemental analysis, IR, powder X-ray diffraction (PXRD), and single crystal X-ray diffraction and thermogravimetric analysis (TGA). Compound 1 consists of dimeric [Cd-2(mu-ppvppa)(2)] fragments linked by 1,4-NDC bridges to generate a 2D honeycomb network. Complex 1 strongly emits blue light in the solid state when excited at 419 Mu at ambient temperature. This emission is selectively quenched by nitro aromatic compounds in water with good sensitivity. Compound 1 also displays recyclable detection of nitro aromatic compounds.
