| 摘 要： | 针对烷氧基取代PPV衍生物存在电子亲合势低的问题,合成了苯环上同时含有给电子和吸电子基团的新型PPV衍生物PPDBPV。提出了新的前驱体合成路线,克服了吸电子基团对苯环的钝化作用给传统合成路线带来的困难。聚合采用Gilch脱卤化氢反应。给出了各步反应的主要工艺条件,探讨了相关因素对单体合成和聚合反应的影响。通过1H-NMR和FT-IR分别对单体和聚合物的结构进行了表征。该聚合物的光致发光谱峰值在650nm处,比PMPPV红移了20nm,波长范围窄,单一性好。

| Abstract: | A novel electroluminescent polymer, Poly (2-Pentyloxy-3,5-Dibromine-1,4-Phenylenevinylene) (PPDBPV) was prepared by the Gilch route. It is so hard to get new precursor by the traditional route because of the inactivation on benzene ring causing by electron withdrawing effect. To resolve the problem, a modified route has been prepared. The polymer and monomers were characterized by 1H-NMR and FT-IR. The synthesis craft had been studied. The maximum Photoluminescence (PL) wavelength of PPDBPV appeared at 650 nm and gave 20 nm red shift comparing with Poly (2-Methoxy-5- Pentyloxy-1,4-Phenylenevinylene) (PMPPV). |
