4,4'-bipyridinium ions form ion-pair charge-transfer (CT) complexes with tetrakis[3,5-bis(trifluoromethyl)phenyl]borate anion with a discrete absorption maximum at 420 nm in methanol and at 475 nm in 1,2-dimethoxyethane. These CT complexes in 1,2\_dimethoxyethane at 20°C show broad structureless lum
