Synthesis of a Cd(II)-based coordination polymer for luminescence detecting 2,4,6-trinitrophenol

A novel Cd(II)-based coordination polymer (CP), {[Cd(adc)(dppc)(H2O)]center dot 2H(2)O}(n) (1), was synthesized by a solvothermal method based on adamantane-1, 3-dicarboxylic acid (H(2)adc) and 3, 6-di(pyridin-4-yl)-9-(4-(pyridin-4-yl) phenyl)-9H-carbazole (dppc). Complex 1 belongs to the monoclinic system with space group C2/c, which exhibits a layer structure. The adjacent layers are extended via weak interactions to form a 3D supramolecular structure. Moreover,1 displayed an excellent photoluminescence property, which can be used as a"turn-off"fluorescence probe to detect 2, 4, 6-trini-trophenol in DMF solution with high selectivity and sensitivity with K-sv of 7.6x10(4) L center dot mol(-1).
