Abstract

We measured the ultrafast third-order optical nonlinearity of

C_{60}

derivatives with multigroups of electron donor,

— {NH}_{2} CN

and

— {(N H}_{2})_{2} CNCN

attached to the

C_{60}

framework. The magnitudes of second-order hyperpolarizability for these two derivatives were estimated at

1.0 \times 10^{- 32} esu

and

3.5 \times 10^{- 32}

esu. The values are several times larger than that for

C_{60}

poly-aminonitrile, which is a monoadduct of

C_{60}

and

— (— {NH}_{2} CN —)_{6}

group, and two orders larger than that for the

C_{60}

molecule.
