摘要
Evidence, based on femtosecond transient absorption and time resolved infrared spectroscopy, is presented for photoinduced charge transfer from the Mo-2 delta orbital of the quadruply bonded molecule trans-Mo-2((TPB)-P-i)(2)(BTh)(2), where TiPB = 2,4,6-triisopropyl benzoate and BTh = 2,2'-bithienylcarboxylate, to di-n-octyl perylene diimide and di-n-hexylheptyl perylene diimide in thin films and solutions of the mixtures. The films show a long-lived charge separated state while slow back electron transfer, tau(BET) similar to 500 ps, occurs in solution.
