摘　　要：采用含氯的前聚物路线合成了聚（２，５－二（十二烷氧基）对苯乙炔）（ＰＤＤＯＰＶ）的前聚物，经热处理得到了具有共轭结构的聚合物。十二烷氧侧基的引入使ＰＤＤＯＰＶ能溶解于许多有机溶剂，如氯仿、四氢呋喃、甲苯等，可制备坚韧透明的自支撑膜。研究了热处理方式对ＰＤＤＯＰＶ导电率的影响，Ｉ２掺杂的ＰＤＤＯＰＶ的最高导电率可达１５Ｓ／ｃｍ。另外，对ＰＤＤＯＰＶ膜和溶液的紫外－可见及荧光光谱进行了初步研究。Poly(2,5-didodecyloxy-p-phenylene vinylene) was prepared through chlorine precursor route followed by the thermal teratment. The introduction of dodecyloxy side groups make PDDOPV soluble in many organic solvents such as chloroform, THF and toluene. Tough and transparent films of PDDOPV can be prepared from these solutions. The conductive property of PDDOPV was affected by the thermal treatment conditions. The conductivity decreases according to the following order of dopants: I_2>FeCl_3>Br_2>H_2SO_4. The conductivity of I_2 doped film is as high as 15 S/cm. The UVVis and PL spectrum of the film and solution of PDDOPV was also studied. The maximum absorbance of PDDOPV appears at 490 nm whereas the maximum intensity of the PL spectrum of PDDOPV film occurs at 580 nm.
