基于四唑功能位点的Tb3+配位聚合物的构筑及其金属离子荧光检测性能
A Tb3+ Coordination Polymer with Tetrazol Functional Sites:Construction and Fluorescent Sensing Property Toward Metal Ions
摘要
Abstract
Lanthanide coordination polymers have been widely investigated in fluorescent sensing owing to their characters in component, structure, and properties.However, the functional targeted construction of lanthanide coordination polymers is still a challenge.Herein, we report the construction, characterization, and properties investigation of a new Tb3+ coordination polymer, namely [Tb(TZI)(DMF)2(H2O)]·(H2O)(1)(H3TZI=5-(1H-tetrazol-5-yl)isophthalic acid and DMF=N,N-dimethylmethanamide).Utilizing the distinct affinities between Tb3+ ion and carboxylate/tetrazole groups, the construction of coordination polymer is well achieved, while the tetrazole group has been introduced into the framework of coordination polymer as sensing sites.As a result, complex 1 reveals ions dependent emissions enhancement owing to the coordination between the ions and the tetrazole sites, which could be utilized for the sensing of Zn2+ and Na+ ions.These results could be instructive for the fluorescent sensing function targeted construction of lanthanide coordination polymers.关键词
