An aggregation-induced emission based “turn-on” fluorescent chemodosimeter for the selective detection of ascorbate ions

Abstract

An aggregation-induced emission (AIE) based “turn-on” fluorescent chemodosimeter for the selective detection of ascorbate ions has been developed, making use of the azide–alkyne “click” reaction between two tetraphenylethene (TPE) derivatives (propergyl–TPE and TPE–azide). The present method offers a rapid, economic and effective way to detect ascorbic acid (Vitamin C) in aqueous media with high selectivity and sensitivity.
