Formation of radical adducts of C60 with alkyl and halo-alkyl radicals. Transient absorption and emission characteristics of the adducts

Abstract

C60 is known to undergo addition reactions with several radicals. Laser flash photolysis and pulse radiolysis studies have been carried out on C60 solutions containing various halocarbons. Transient absorption peaks observed in pulse radiolysis experiments at 460 and 640 nm are attributed to different radical adducts between C60 and halocarbon radicals. No evidence is obtained for the radical cation C60˙+. On a longer timescale (ca. 30 µs), a unique strong emission is observed with a maximum at 745 nm which is attributed to the excited state of C60 radical adducts generated owing to absorption of the strong probe light. Rate constants for the formation and decay of the radical adducts have been estimated and compared with some reported values.
