采用紫外 -可见光谱跟踪用直接聚合法制备可溶的聚对苯乙炔衍生物的反应过程 ,结果表明反应仍然经历了生成前聚物的过程。控制反应条件使聚合反应首先生成前聚物 ,在前聚物烯化反应阶段加入起增溶作用的长链醇 ,得到了具有良好的溶解性的、主链中含非共轭链段的聚对苯乙炔衍生物。用该聚合物制备的电致发光器件 ,在 5 -6V电压驱动下发光 ,发光峰位于 5 80nm左右。
The UV-Vis spectra were used to trace the reaction of the poly (p-phenylenevinylene) derivatives prepared by the direct polymerization method. The results showed that the reaction still underwent the process of forming the prepolymer. The reaction conditions are controlled so that the prepolymer is first formed in the polymerization reaction and the long-chain alcohol which acts as a solubilizing agent is added in the pre-polymerization step of olefination to obtain a polymer with good solubility in the main chain Phenylacetylene derivatives. Electroluminescent device prepared with this polymer, driven by a voltage of 5 -6V, the emission peak is about 580nm.
