可溶性聚(2-甲氧基-5-辛氧基)对苯乙炔的合成及其导电和三阶非线性光学性能
摘要:
通过双醚化反应、氯甲基化反应和在强碱性条件下进行的脱氯化氢反应,制备出可溶性聚(2-甲氧基-5-辛氧基)对苯乙炔(PMOCOPV)。利用红外光谱(IR)、紫外可见吸收光谱(UV-Vis)、核磁共振谱(1H NMR)和凝胶渗透色谱(GPC)对产物PMOCOPV的结构进行了表征。将I2、Br2、FeCl3和H2SO4作为掺杂剂,对PMOCOPV进行掺杂反应,得到了电导率分别为47.2、21.6、32.5和27 S/cm的掺杂态PMOCOPV。采用简并四波混频(DFWM)方法研究了PMOCOPV的三阶非线性光学性质。研究发现,PMOCOPV具有大的三阶非线性光学效应,在532 nm下的共振三阶非线性极化率和1064 nm下的非共振三阶非线性极化率χ(3)分别为6.8×10-10 esu和1.2×10-11 esu。

Synthesis of A Soluble Poly(2-Methoxy-5-Octyloxy)-1, 4-Phenylene Vinylene and Its Conductive and Third-Order Nonlinear Optical Properties
Abstract:
A soluble poly (2-methoxy-5-octyloxy)-p-phenylene vinylene (PMOCOPV) was synthesized through double etherification,chloromethylation and dehydrochlorination reactions.The structure of the PMOCOPV has been characterized by IR,UV-Vis,1H NMR and GPC.The conductivity of I2,Br2,FeCl3 and H2SO4 doped PMOCOPV was 47.2,21.6,32.5 and 2.7 S/cm,respectively.The third-order nonlinear optical property of PMOCOPV was studied by degenerate four-wave mixing (DFWM).The resonant value of 6.8×10-10 esu at 532 nm and the off-resonant value of 1.2×10-11 esu at 1064 nm of third-order optical nonlinear susceptibilities were measured respectively.
