| Abstract | Steady-state absorption/Ñuorescence spectra and time-resolved absorption/Ñuorescence spectra were measured to investigate the photoexcited states properties of N-methylpyrrolidinofullerenes [R\ H (1), (2), (3), 6036 64 642 (4), (5)]. Functionalization causes bandshifts to longer wavelength for absorption and Ñuorescence 64 642 spectra, accompanied by enhancements in the Ñuorescence quantum yields in nonpolar solvents. The triplet (T) states of these derivatives show very similar properties (quantum yields, molar absorption coefficients and quenching) to whereas TÈT 2 60 absorption bands shift to short wavelength and the lowest triplet energies decrease compared with those of Derivative 5, 60 . which has a strong electron-donating group, shows a prominent solvent polarity e†ect on the Ñuorescent quantum yield and lifetime, and triplet formation, suggesting that intramolecular charge transfer takes place. |
