Triisocyano-based trinuclear gold(I) complexes with aggregation-induced emission (AIE) and mechanochromic luminescence characteristics

摘要

Three novel trinuclear gold(I) complexes have been designed and synthesized. These gold(I) complexes exhibit aggregation-induced emission characteristics. Furthermore, the photoluminescence properties of these luminogens show off-on green fluorescence in response to mechanical grinding. The changing of weak multiple intermolecular C-H center dot center dot center dot F or pi-pi interactions, or the formation of aurophilic interactions are possibly responsible for their mechanochromism phenomena.
