a Individual molecular excitations. b, c CT mixed collective intermolecular couplings. At low molecular surface densities (b), long-range and delocalized excitonic couplings can occur, as indicated by the gray arrow. “E” represents energy transfer. Besides, at high molecular surface densities (c), short-range intermolecular CT can occur simultaneously, as denoted by the blue straight arrow. Only the molecules chemically-adsorbed to the metal surface are displayed for clarity.
