摘　　要：采用分子设计的思想 ,合成了一种分子主链由离子传导链段 2 4 -冠 - 8和共轭发光链段 1,5 -二苯乙烯基萘组成的新型交替结构的发光聚合物 ,并用多种手段对其结构进行了表征 .实验结果表明 ,该聚合物具有优异的溶解性能 ,可以溶于苯、甲苯、二甲苯、四氢呋喃、乙腈等诸多有机溶剂中 ,并均可采用旋转涂覆法形成均匀、透明、几无针孔的薄膜 .并采用该聚合物成功地制备了结构为 ITO/ PEDOT/聚合物 +L i CF3SO3/ Al和 ITO/ PEDOT/聚合物 +L i CF3SO3+PEO/ Al的 2种发光电化学池器件 .A novel light-emitting copolymer, containing alternating ionic conductive segments, 24-crown-8, and light-emitting conjugated segments, 1,5-distyrylnaphthalene, has been synthesized. The structure of the copolymer was verified using various methods. The copolymer has good solubility in many organic solvents, such as benzene, toluene, xylene,acetonitrile etc. and shows excellent film-forming property. The polymer solution can be spin-coated onto various substrates giving highly transparent and homogeneous thin films. Light-emitting electrochemical cells with configurations ITO/PEDOT/polymer+LiCF 3SO 3/Al和ITO/PEDOT/polymer+LiCF 3SO 3+PEO/Al have been successfully fabricated.
