A highly selective fluorescence turn-on detection of cyanide based on the aggregation of tetraphenylethylene molecules induced by chemical reaction

Chem Commun (Camb). 2012 Dec 28;48(100):12195-7. doi: 10.1039/c2cc37094h.

Abstract

A new selective and sensitive fluorescence turn-on detection of CN(-) is reported by taking advantage of aggregation induced-emission (AIE) behavior of tetraphenylethylene units and the nucleophilic attack of CN(-) on the indolium group in compound 1.
