The synthesis of divinyl liquid crystalline monomer 4-undecenyloyloxybenzoyl-4'-allyloxybenzoyl-p-benzenediol bisate and network polymers was described. The chemical structures of the synthesized monomer and network polymers were confirmed by FT-IR spectrum.

以双烯类液晶单体4-十一烯酰氧基苯甲酸-4'-烯丙氧基苯甲酸对苯二酚双酯为交联剂，通过与聚矽氧烷接枝反应，合成了系列网络聚合物P1~P5。

Here we introduced oxadiazole moiety to theside-chain of Ph-PPV to enhance the electron transport properties. The luminescenceefficiency and luminescence brightness (1.33cd/A, 9400 cd/m~2) of the Ph-PPV withside oxadiazole moiety are much higher than non-oxadiazole Ph-PPV (0.70 cd/A,2300 cd/m~2), and these polymers emitted green light which unaffected by theintroduction of oxadiazole moiety. Anthracene has a rigidity and planar structure which shows high photoluminescenceand thermo-stability.

结果表明，以十烷氧基作为间隔基使噁二唑单元键接在苯基取代PPV的侧链，所得材料制备的电致发光器件的效率和亮度(1.33cd／A，9400 cd／m~2)明显高于不含噁二唑单元的苯基取代PPV(0.70 cd／A，2300 cd／m~2)，噁二唑单元的引入并不影响材料的发光光色，膜状态下的荧光发射光谱和电致发光光谱均呈绿光发射。
