A dramatic elongation of the lifetime of charge-separated state by complexation with yttrium triflate in ferrocene-anthraquinone linked dyad.
Seven million times elongation of the lifetime of charge-separated state is attained in the presence of yttrium triflate [Y(OTf)3] in the photoinduced electron-transfer reaction of a ferrocene-anthraquinone dyad (Fc-AQ) with a rigid amide spacer in benzonitrile at 298 K as compared with the lifetime in its absence. Such remarkable elongation of the CS lifetime in the presence of Y(OTf)3 results from the strong binding of Y(OTf)3 with the AQ*- moiety of Fc+-AQ*-.
