New types of precursor polymers for poly(arylene vinylene) (PAV) were synthesized with the aims of attaining very high molecular weight and suitable stabilities.Highly oriented films of poly(2,5-dimethoxy-p-phenylenevinylene) (MOPPV) and poly(2,5-thienylenevinylene) (PTV) could be prepared through investigation on the effects of degree of conversion from precursor to PAV and temperature on chain orientations in the films. Chain orientations in the films were evaluated by the spectroscopic methods. Strong anisotropies were observed in the electronic conductivity, photo-conductivity, and third order nonlinear susceptibility chi^<(3)> of the oriented films. Conductivities along chain orientation direction have much higher values than those perpendicular to the direction by the factor of 5. The values of (3) along the orientation direction in MOPPV and PTV films are extremely high compared with those of other organic materials and exceeded 10^<-10> e.s.u.

合成了新型聚芳撑亚乙烯基（PAV）前驱体聚合物，通过研究前驱体转化率和温度对膜中链取向的影响，制备了高取向的聚（2，5-二甲氧基对苯撑亚乙烯基）（MOPPV）和聚（2，5-噻吩撑亚乙烯基）（PTV）膜。通过光谱方法评估了薄膜中的链取向。取向膜的电导率、光电导率和三阶非线性极化率χ ^<（3）>具有很强的各向异性。沿沿着链取向方向的电导率比垂直于该方向的电导率高5倍。MOPPV和PTV膜中的（3）沿着取向方向的值与其它有机材料相比非常高，超过10 μ <-10>e.s.u.。
