中文摘要：
从聚合物结构修饰、复合/共混以及合成工艺等方面概述了近十多年来聚对苯撑乙烯衍生物的研究进展和发展趋势。为获得高效、稳定、可溶的PPVs型有机光电材料，可通过引入吸电子基团（如氟原子、氰基、含氮杂环等）等对其结构进行修饰来改善其平衡电荷传输的能力进而提高其发光效率；同时，通过引入长链取代基和液晶单元结构来兼顾聚合物的溶解性和稳定性，以提高材料的可加工性和器件的稳定性。通过复合／共混可以控制聚合物膜的聚集态来提高发光效率。
英文摘要：
Poly-（ p-phenylene vinylene）s （PPVs） luminescent materials was reviewed. The efficiency, processibility and stability of electroluminescent materials are three key factors that should be considered. PPV is a poor electron acceptor. To overcome the imbalance of electrons and holes transporting, the most frequently used solutions are either to use additional organic charge-transporting layers between the emissive layer and the electrodes or to adjust the energy level of the polymer by means of attaching electron-withdrawing groups （such fluorine and nitrogen-containing heterocycle） to the polymer backbone. Next, bulky substituent groups or chains may help to increase the solubility. Introduction of bulky aromatic rings to the conjugated polymer as cyano, long side backbone usually may improve the stability. Finally, the efficiency was enhanced through co-polymerization and composite
