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)(H2O)]·2H2}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Ksv可达7.6×104 L·mol-1。 |

Abstract: A novel Cd(Ⅱ)-based coordination polymer (CP), {[Cd(adc)(dppc)(H2O)]·2H2O}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). Complex1 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 Ksv of 7.6×104 L·mol-1. |
Keywords: carbazole coordination polymer Cd(Ⅱ) luminescence detecting nitroaromatic compounds |
