Synthesis,Crystal and Fluorescence Property of 2-D Coordination Polymer {[Cd(btmb)(1,4-bdc)_2·H_2O·CH_3OH]}_n

将联苯二苄苯并三氮唑(btmb)和对苯二甲酸(1,4-bdc)与CdSO4进行混配,得到了二维网状配位聚合物{[Cd(btmb)(1,4-bdc)2.H2O.CH3OH]}n.X射线单晶衍射分析表明,该化合物为蜂窝状的二维(6,3)网状聚合物结构,每个Cd(Ⅱ)离子作为三连接节点,通过1个联苯二苄苯并三氮唑和2个对苯二甲酸根离子桥联而成.测定了该配位聚合物及配体(btmb)在DMF溶液中的荧光性能.

A new 2-D coordination polymer {[-Cd（btmb）（1,4-bdc）2·H2O·CH3OH]}n is synthesized by the reaction of 4,4＇-bis（henzotriazole-l-ylmethyl）biphenyI （btmb） and terephthalate （1, 4-bdc） with CdSO4·8H2O. X-ray diffraction technique reveals that the Cd^2＋ centres act as three- connected nodes and a 2-D（6,3） distorted honeycomb coordination network is formed. The fluorescence properties of the title complex and the pure ligand btmb are determined in DMF solution.
