Macrocyclic C,C′-diaryl-o-carborane derivatives containing pseudo-crown ether: emission enhancement upon cation recognition

Abstract

We report the aggregation-induced emission (AIE) properties of macrocyclic C,C′-diaryl-o-carborane derivatives and modulation of the luminescence properties by adding cations through the regulation of excited-state structural relaxation. It was demonstrated that the emission enhancement and suppression of the non-radiative decay process can be induced upon cation recognition.
