PDI moieties, affords the charge-separated (CS) state, which was clearly detected by its transient absorption spectrum in femtosecond laser flash photolysis measurements. The CS lifetime was determined to be 26 ps. The addition of Mg(ClO4)2 to a benzonitrile solution of 2 and the photoexcitation affords the long-lived CS state with the lifetime of 480 μs, whereas no such long-lived CS state was formed
