摘　　要：以1,3-金刚烷二甲酸(H2adc)和3,6-二(4-吡啶基)-9-(4-吡啶苯基)-9H-咔唑(dppc)为配体,通过溶剂热法构筑了一个新型的Cd(Ⅱ)基配位聚合物:{[Cd(adc)(dppc)(H_(2)O)]·2H_(2)O}_(n)(1)。配合物1属于单斜晶系,C2/c空间群,具有二维层状结构,相邻的层与层之间通过氢键等弱相互作用形成一个三维超分子结构。1具有良好的荧光性,能够对DMF溶液中的2,4,6-三硝基苯酚实现高灵敏、高选择的荧光猝灭检测,其K_(sv)可达7.6×10^(4)L·mol^(-1)。A novel Cd(Ⅱ)-based coordination polymer(CP),{[Cd(adc)(dppc)(H_(2)O)]·2H_(2)O}n(1),was synthesized by a solvothermal method based on adamantane-1,3-dicarboxylic acid(H2adc)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.More-over,1 displayed an excellent photoluminescence property,which can be used as a“turn-off”fluorescence probe to detect 2,4,6-trinitrophenol in DMF solution with high selectivity and sensitivity with Ksv of 7.6×10^(4)L·mol^(-1).CCDC:2233682.
