摘要：

A new fluorescent chemosensor 5-(P-N,N'-bis(2-pyridyl)amino)phenyl-10,15,20-tris(p-methoxyphenyl)porphyrin zinc has been designed and synthesized by the Ullmann-type coupling. It displays high selectivity for Cu2+ ion and exhibits fluorescence quenching upon binding of Cu2+ ion with an "on-off" type fluoroionophoric switching property, and its fluorescence can be revived by addition of EDTA disodium solution.
