通过Suzuki缩聚反应合成了含电子传输、空穴传输和蓝光发射单元的共轭聚合物。这些共聚物表现出优异的热稳定性和光学稳定性。光学性质研究表明，在聚合物主链中引入螺联荧烯单元可以显著增加聚合物的有效共轭长度。电化学研究表明，螺联荧烯单元的引入可以提高电极的电化学稳定性，改善其电子和空穴注入能力。电致发光结果还表明，螺联荧烯单元的引入可以显著提高器件的性能。#2008威利期刊公司J Polym Sci Part A：Polym Chem 46：1349-1356,2008
Conjugated polymers containing electron-transporting, hole-transporting, and blue light-emitting units were synthesized by Suzuki polycondensation. These copolymers exhibited excellent thermal and optical stability. Optical investigation indicated that the incorporation of the spirobifluorene units in the polymer main chain could markedly increase the effective conjugation length of polymers. Electrochemical studies showed that the incorporation of spirobifluorene unit could raise the electrochemical stability and improve the electron- and hole-injecting abilities. The electroluminescent results also showed that the introducing of spirobifluorene units could significantly improve the device performance. © 2008 Wiley Periodicals, Inc.
