聚（2，5-二丁氧基）對苯乙炔的制備及其光電性能

A new style photoelectric functional material poly (2, 5-dibutyloxy)-p-phenylene vinylene (PDBOPV) is synthesized through bisetherification, chloromethylation and dehydrochlorination reaction. The structure of PDBOPV is characterized by ultraviolet-visible absorption spectrum. There exists π-π electronic transition of benzene ring and unsaturated C=C bond in vinylidene of PDBOPV at 310 and 520 nm through ultraviolet-visible absorption spectrum. The conductivity of I2, Br2, FeCl3 and H2SO4 doped PDBOPV is 52.6, 27.3, 38.4 and 6.1 S/cm, respectively. The third-order nonlinear optical property of PDBOPV is studied by degenerate four-wave mixing method. The resonant value of 7.2×10^(-10)esu at 532nm and the off-resonant value of 1.6×10^(-11)esu at 1064nm of third-order optical nonlinear susceptibilities are measured, respectively.
