Fullerenes as energy transfer acceptors ,[object Object],[object Object]

Fullerenes as energy transfer donors ,[object Object],[object Object],[object Object],The triplet state of C60 can undergo a very efficient triplet energy transfer to a ground state triplet oxygen molecule transferring it into a very reactive singlet oxygen molecule.

Energy transfer from an organic molecule to a fullerene ,[object Object],[object Object],[object Object],These works underline the competing nature of the two processes that are often simultaneously possible in a system of two organic chromophores in close contact.
