摘要：

Several important photophysical properties of the fullerene C70 have been determined. Fluorescence is weak but measurable. The yields of triplet C70 and of singlet oxygen are high, but not quite quantitative; the triplet energy is slightly above 33 kcal/mol. The triplet has an absorption spectrum that resembles that of C60 in some respects but is somewhat stronger and lacks a strong red-infrared absorption present in the C60 spectrum. Overall, the behavior Of C70 is similar to that of C60, but the lower symmetry relaxes the forbiddenness of some absorption and emission processes.
