【Abstract】 A novel conjugated hole transport polyazomethine containing 4,4’-bisamine- triphenylamine has been synthesized by polycondensation, which has non-crystalline, heat resistance stability, hole transport properties, and has been characterized by IR, UV-Vis, and 1HNMR spectrum. The XRD result indicated that no crystalline phase . The thermal stability of the polymers was conducted by thermal gravity (TG) and differential thermal analysis (DTA). The ionization energy and frontier linear molecular orbital level were calculated by quantum chemical calculation, which indicated good hole transportation properties. The third-order optical nonlinear susceptibility χ(3) has shown that nonlinearity is dominated by the resaturation or two-photon absorption in PSB. The sign and nonlinear absorption index have been measured at 532nm, 5ns-duration pulses to be χreal(3)= ? 1. 35×10?11esu,β=4.19×10-11m/W , corresponding nonlinear refractive index n2 = ? 1 .4×10?10esu,by the Z-scan method.更多还原
