Research Advance in Some Electroluminescent Polymers

介绍了几种典型的电致发光聚合物材料,包括聚(对苯乙烯撑)及其衍生物、聚噻吩及其衍生物、聚芴及其衍生物,对它们的结构、制备方法、特点进行了归纳和讨论。其中最重要的是聚(对苯乙烯撑)(PPV)及其衍生物,目前采用较多的制备方法是前聚物法和强碱诱导的去卤缩合法以及电化学聚合法。在苯环上引入长链烷烃、烷氧基或芳基后的取代PPV,即PPV的衍生物,可溶于很多有机溶剂。可溶性PPV衍生物为制备多层电致发光聚合物器件提供了有效途径。文章还对电致发光聚合物材料存在的问题和发展前景进行了探讨和展望。

The recent research progress on some electroluminescent polymers including poly(p-phenylenevinylene), polythiophene, polyfluorene, and their derivatives is reviewed. The preparation,structure and properties of these materials are introduced. It put emphasis on poly(p-phenylenevinylene) and its derivatives. Among the preparation methods, precursor polymerization, condensation of halide in existence of alkali, and electrochemical polymerization are often used. Soluble alkyl-substituted, alkoxyl-substituted or phenyl-substituted poly(p-phenylenevinylene)s, i. e., poly(p-phenylenevinylene) derivatives are synthesized and can be soluble in diffferent kinds of solvents. Soluble poly(p-phenylenevinylene) and its derivatives provide effective ways to prepare electroluminescent devices. The exiting problems and future of electroluminescent polymer materials are also described.
