摘要：

New symmetrical pi-conjugated molecules having large third-order nonlinear susceptibilities, chi(3), are reported. The chi(3) spectra of these molecules have been measured by a THG Maker-fringe method. The magnitudes of the three-photon resonant chi(3) reach 10(-10) esu. The positions of the three-photon resonance lie at the lowest-energy peaks in the vibrational structure of each absorption spectra for these molecules.
