Abstract

A new chemosensor for Cu2+ based on Schiff base with high sensitivity and selectivity was designed and synthesized. The fluorescence intensity of the chemosensor in CH3CN solution was enhanced 160-fold after the addition of 10 equiv. Cu2+ over other metal ions. In addition, it also facilitates colorimetric detection for Cu2+ in CH3CN solution. The chemosensor displayed low detection limit and fast response time to Cu2+.
