Abstract

Electroabsorption spectra of electron donating butyloxy- (OBu) or electron withdrawing butylsulfonyl (SO₂Bu)-substituted tribenzotetraazachlorin (TBTAC)-C₆₀ conjugates (1 and 2, respectively) have demonstrated that significant change of the molecular polarizability is associated with the photoexcitation of 1 in the lower energy region, while that in the higher energy region is comparable with the corresponding band of 2, although the π-aromatic structures of 1 and 2 are identical to each other, being consistent with the previously reported result of the DFT calculations.
