摘要Third-order optical nonlinearity of a novel copper phthalocyanine--ferrocene dyad is measured by femtosecond forward degenerate four-wave mixing (DFWM) technique at 800nm. The second-order hyperpolarizability of the novel copper phthalocyanine--ferrocene dyad is measured to be 1.74×10-30 esu. This large and ultrafast third-order optical nonlinear response is mainly enhanced by the formation of intramolecular charge-transfer which can enhance the delocalized movements of the large π-electrons in the molecules.
