The photochemical reactions of C 6 0 with solvated electrons and triethylamine (TEA) were studied by a nanosecond transient absorption method. Transient solvated electrons (e s - ) were prepared by the 308 nm laser photoionization ofN,N,N ,N -tetramethyl-p-phenylenediamine (TMPD). The removal rate constant of e s - was determined to be (2.6 ± 0.4) 10 9 M - 1 s - 1 in a mixed solvent consisting of 2-propanol and benzene. The electron capture by C 6 0 is responsible for the removal process. The C 6 0 molecule in the S 1 state reacts with triethylamine with a rate constant of (3.3 ± 0.3) 10 9 M - 1 s - 1 to form an exciplex, which generates a stable product.
