中文摘要： 优异的蓝色发光材料仍是发光共轭聚合物领域中尚未解决的问题。如何实现较宽带隙下的载流子（电子、空穴）平衡注入与传输是该类材料中的关键科学问题，而新型双极性共轭聚合物结构的设计与合成是解决该问题的有效途径。申请人在前期工作的基础上，提出利用具有双极性功能的宽带单体菲并咪唑衍生物构建蓝光聚合物的方案。通过调节双极性单体反应底物结构，利用高效的"一锅法"一步合成各类的菲并咪唑衍生物结构，完成单体取代基团结构的改变的同时，既能够实现对其载流子注入/传输能力的调节，又可满足聚合物单体高分子官能化和结构功能（烷基化等）修饰的多重要求。本项目通过对双极性单体结构、主链连接方式和修饰基团的调节制备了一系列新型双极性蓝光聚合物，研究单体结构对聚合物性能影响规律，实现该类聚合物在高效蓝光前提下载流子注入/传输平衡，发展一类新型的宽禁带双极性单体结构在电致蓝光聚合物制备中的应用。

英文摘要： The problem has not yet been resolved to gain an excellent blue light-emitting polymer in conjugated light-emitting polymer field. It is a key scientific issue to realize the balance of the carriers ( Hole and Electron ) injection and transport in the wide-band-gap emission materials. Reacently, there is an effective way to solve the problem by inserting the hole and electron fution groups to the polymer, constructing a bipolar conjugated polymer. Based on preliminary work, the applicant proposed a program of building this kind polymer only containing phenanthroimidazole (PIM) group, which show a wide-band-gap and bipolar character by the proper choice of substitutional group. Adjusting the structure of reaction substrate to a PIM derivative, the substituent of the bipolar monomer has been changed. This change might influence the charactertion of carrier injection / transport ability, at same time, and the derivative could tune to the monomer for polymerization with a multiply structure modification such as alkylation. In this project, we would prepare a series of new bipolar blue polymer by changing the bipolar monomer structures, or the link way of polymerization or the modified groups. The regularity of the monomer structure to the polymer properties should be discussed as a point. The methold would be esta
