摘要：

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. (C) 2008 Wiley Periodicals, Inc.
