摘要：

Solutions of the fullerene C-60 and a substituted naphthalene give rise to a new absorption band that is not observed from solutions containing only C-60 or the naphthalene. The absorption maximum of this new band successively shifts to a longer wavelength as the ionization potential of the naphthalene decreases. These data reflect a C-60-naphthalene cooperative absorption from a ground-state contact complex to form an excited-state complex with charge-transfer character. This excited-state C-60-naphthalene complex decays to yield the localized C-60 singlet excited state which, in turn, yields the C-60 triplet state with approximately unit efficiency.
