新型4-氟水杨酸双核铜配合物的合成及其荧光性能
Chinese Journal of Synthetic Chemistry(2015)
Abstract
以4-氟水杨酸(H2foac)和2,2'-联吡啶(bipy)为原料,甲醇和水为溶剂,醋酸铜为离子源,采用溶剂热法合成了一个新型的双核铜配合物{[Cu2(foac)2(bipy)2]·3H2O(1)},其结构和荧光性能经IR,FL,元素分析和X-射线单晶衍射表征.1属三斜晶系,Pi空间群,晶胞参数a=8.198(2)(A),b=9.986(3)(A),c=11.814(4)(A),α =91.45(3)°,β=105.78(2)°,γ=92.87(3)°,V=928.8(5)(A)3,Z=1,Dc=1.433 g· cm-3,μ=1.210mm-1,F(000) =408.1中两个Cu(Ⅱ)分别与bipy的两个氮原子,foac2-的两个氧原子及另一个foac2-的桥联氧原子配位形成扭曲的四方锥配位环境.在375 nm激发波长激发下,1的发射峰位于390nm.
