Abstract:

We have synthesized the C60 aminonitrile and dicyandiamide derivatives and their Fe(Ⅲ)complex. The second-order hyperpolarizability γ for these derivatives have been measured by using the femtosecond optical Kerr effect at 810 nm. The relation between the value of γ and the characteristic of charge transfer has been investigated.

Key words: C60 derivative, Third-order optical nonlinearity, Charge transfer
