摘要：
A new nematic-like mesophase photoconductive polymer PPT-TPA consisting of wholly aromatic rigid backbone of poly(p-phenyleneterephthalate),PPT and pendent hole-transporting (TPA) groups attached to the ends of oxyalkyl spacers has been synthesized. The correlation between the mesophase structure and the optical/physical properties of the photorefractive composite is investigated by X-ray diffraction, and photorefractive experiments. Despite a lower photoconductivity of the new photorefractive PPT-TPA composite, this material shows a higher photorefractive previously sensitivity S-n2 = 2 +/- cm 0.2cm(2)/kJ at E = 50 V/mu m than the previously synthesized PPT-CZ composite with a different photoconducting groups that exhibits a highly-ordered layered structure.
