具有8-重互穿的金刚石拓扑构型的MOF的合成与Hg^(2+)荧光检测

Synthesis and Hg^(2+) Fluorescence Detection of MOF with 8-repenetrating Diamond Topological Structure

采取混合配体的合成策略,通过溶剂热的方法,设计、合成了一个结构新颖的金属有机骨架化合物[Zn(bpde)(bims)](H_(2)bpde=4,4′-二苯乙烯二羧酸,bims=4,4′-双咪唑-2,2′-砜)。该化合物呈现结构新颖的8-重互穿的金刚石拓扑网络结构。研究发现,该化合物可以作为一种“turn-on”型荧光探针高选择性地检测水溶液中的金属汞离子,其荧光增强常数K_(sv)=2.222×10^(4)L/mol。

In this paper,a novel mental organic framework[Zn(bpde)(bims)](H_(2) bpde=4,4′-stilbene dicarboxylic acid,bims=4,4′-bisimidazyl-2,2′-sulfone)was designed and synthesized by solvothermal method using a mixed-ligand strategy.This compound shows an eight-fold interpenetrating of dia network.The result shows that this compound can be used as a“turn-on”type fluorescent probe for highly selective detection of metal mercury ion in aqueous solutions,with K_(sv)=2.222×10^(4)L/mol.
