    • Perylene-based CP 12f present only one band with the typical vibronic structure, so it could not be used for association constant determination through excimer formation, because its characteristic lower energy peak than the monomer emission could not be detected even at high concentration. This was attributed to the short lifetime and low quantum yields of the perylene moiety, which precludes the excimer formation and detection if it is not previously preformed
