Abstract

Abstract : A pentiptycene-containing Au(i ) complex reveals the supramolecular factors behind the luminescence and displays solvent-dependent aggregation-induced emission and luminescence vapochromism and mechanochromism. Abstract : Four crystalline (pseudo)polymorphs of [Ph–Au–CN–Phip –OC8 H17 ] (1 ), where Phip = central phenylene of pentiptycene, reveal that the π-backbone conformation relative to the Au⋯Au bonding axis is important in determining the energy and efficiency of the supramolecular luminescence, which offers mechanistic insights into the luminescence mechanochromism and vapochromism and the solvent-dependent aggregation-induced emission (AIE) of 1 .
