摘要
By means of quantum chemical calculations, the deactivating reactions of triplet excited state C-60 by beta-carotene were explored from the thermodynamic point of view. The solvent effect on the deactivating mechanisms was also discussed. Primarily, the energy transfer from triplet excited state C-60 to beta-carotene is feasible both in benzene and water. Secondly, beta-carotene may also deactivate triplet excited state C-60 through electron transfer from ground state beta-carotene to triplet excited state C-60 or from triplet excited state beta-carotene to triplet excited state C-60 in water, while only the latter pathway is thermodynamically favorable in benzene.
