The triplet excited state behavior of C[sub 84] has been probed by the triplet - triplet energy transfer method using pulse radiolytically generated biphenyl triplets in benzene. The triplet excited state has a weak absorption in the UV (difference absorption maxima at 310 and 345 nm) but no significant absorption in the visible. The rate constants for energy transfer from [sup 3]BP* and [sup 3]C[sub 60]* are 4 [times] 10[sup 9] and 4.7 [times] 10[sup 9] M[sup [minus]1] s[sup [minus]1], respectively. Triplet excited state properties of [sup 3]C[sub 84]* are compared with other fullerenes. A photocatalytic method has also been successfully employed to reduce C[sub 84] in a UV-irradiated colloidal TiO[sub 2] suspension. 36 refs., 4 figs., 1 tab.
