Abstract

Efficient aggregation induced phosphorescence emission (AIPE) of an ionic Ir(iii) complex occurs when the counterion (PF6(-)) is exchanged specifically by ClO4(-) in aqueous media. As a result, a rapid, highly selective "turn-on" phosphorescent response to ClO4(-) is observed in aqueous media. These studies pave the way for a new efficient phosphorescence-based detection strategy for anions.
