PolySchiff base containing triphenylamine has been synthesized by polycondensation and characterized by FT-IR, NMR, UV-visible spectrometer. Measurements of the third-order optical nonlinear susceptibility x(3)by Z-scan technique have shown that the large nonlinearity is dominated by the two-photon absorption in PSB. The sign and size of real part Rex(3), nonlinear refractive index n2 have been measured with the condition of 532 nm, 8 ns-duration pulses to be -1.23x10-10esu, -3.06x10-12esu;nonlinear absorption index β and size of image part Imx(3) to be 3.63x10-10 m/W, 1.15x10-11 esu, respectively, so the third-order nonlinear susceptibility x(3) is 1.19x10-11 esu. The value is larger than other polymers reported. PSB is self-focusing material and has potential application in nonlinear optic field.
