Inter- and intramolecular photoinduced electron-transfer processes between C60 and diphenylaminofluorene in solutions

Article Abstract:

The photoinduced charge separation and lifetime of the radical ion pair of the new dyad have been investigated by laser flash photolysis methods. Quenching of the fluorescence intensities and the observed short fluorescence lifetimes of the C60 moiety of the dyad in benzonitrile (PhCN) and DMF indicated that charge separation takes place via the singlet excited state of the C60 moiety at a fast rate with high efficiency.

Photoinduced charge separation and charge recombination in the [60]fullerene-diphenylbenzothiadiazole-triphenylamine triad: Role of diphenylbenzothiadiazole as bridge

Article Abstract:

A study on photoinduced electron-transfer processes of the newly synthesized [60]fullerene-diphenylbenzothiadiazole-triphenylamine (C(sub 60)-PBTDP-TPA) triad in polar and nonpolar solvents was performed. The role of the PBTDP-TPA moiety with twisted intramolecular charge-transfer character playing as energy donors and electron donors in addition to the bridge is disclosed.
