Abstract
Charge transfer complexes between C60 and ternary aromatic amines (N,N,N,N′-tetramethyl-p-phenylenediamine,p-methoxy-N,N-dimethylaniline,p-methyl-N,N-dimethylaniline,N,N-diethylaniline,N,N-dimethylaniline, and triphenylamine) were studied in chlorobenzene solutions. The lifetimes of the excited state with charge transfer in these complexes were measured by the method of picosecond laser photolysis. The dependence of the rate constant of the back electron transfer on ΔG in the back electron transfer reaction with relaxation of the charge-transfer state exhibits the “Marcus-inverted” region.
