Synthesis and Properties of Metal-Organic Framework(MOFs)with Dual Fluorescence Emission
In recent years,the MOFs ratio fluorescence sensor with dual emission has attracted wide attention because of its self-calibration ability against environmental interference.Herein,the polycarboxylic acid ligand(H2TPYAN)functionalized with anthracene was synthesized by introducing the organic lumines-cent molecule(anthracene)into the terpyridine polycarboxylic acid ligand.With H2TPYAN,a novel Cd-based MOFs(Cd-TPYAN)was assembled.The analysis results of single crystal structure confirmed that Cd-TPYAN is a three-dimensional metal-organic framework with pore structure,and anthracene mole-cules are oriented in the pore.Cd-TPYAN can produce dual fluorescence emission at 350 and 446 nm un-der the excitation of 290 nm.
