Abstract:
Four crystalline (pseudo)polymorphs of [Ph-Au-C[triple bond, length as m-dash]N-Phip-OC8H17] (1), where Phip = central phenylene of pentiptycene, reveal that the π-backbone conformation relative to the AuAu 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.
