Photoinduced electron-transfer processes of the newly synthesized [60]fullerene-diphenylbenzothiadiazole-triphenylamine (C-60-PBTDP-TPA) triad in polar and nonpolar solvents have been studied by using time-resolved transient absorption and fluorescence measurements from picosecond to microsecond regions. By fluorescence lifetime measurements in picosecond time regions, excitation of the charge-transfer transition of the PBTDP-TPA moiety in C-60-PBTDP-TPA induces energy transfer to the C-60 moiety generating C-1(60)*-PBTDP-TPA, competitively with charge separation generating C60center dot-PBTDP-TPA(center dot+). From C-1(60)*-PBTDP-TPA, which is generated directly and indirectly, charge separation occurs generating C-60(center dot-)-PBTDP-TPA(center dot+) in polar solvents. The C-60(center dot-)-PBTDP-TPA(center dot+) formed via the singlet excited states decayed within a few nanoseconds as revealed by the picosecond transient absorption spectra. In the nanosecond time region, C60PBTDP-TPA(center dot+) is produced slowly, probably via C-3(60)*-PBTDP-TPA. Lifetimes of such slowly generated C-60(center dot-)-PBTDP-TPA(center dot+) were longer than 1 mu s, which are the longest values among the C-60-bridge-TPA triad systems reported hitherto at room temperature. Roles of the PBTDP-TPA moiety with twisted intermolecular charge-transfer character playing as energy donor and electron donor in addition to the bridge have been disclosed.
