Abstract
The characteristic absorption bands disappear and the shortest band at ∼244 nm in cyclohexane or 282 nm in toluene remained only with long smoothing tail as C 60 reacts adequately with aliphatic amines under sunlight radiation at ∼40 °C. Simultaneously, fluorescence emission shifts from a weak band initially at longer wavelength to another strong one finally at shorter wavelength. The results might imply that the π-conjugation system of C 60 parent molecule is isolated into smaller separated parts. Therefore, some possible isolation models associated with observed experimental results are designed under some reasonable assumptive conditions.
