项目摘要

The final target of the project is to establish the method to fabricate electroluminescent (EL) devices using vacuum-sublimation polymerization technique. Thus the studies on the design of monomers and polymer suitable for vacuum-vapor polymerization, development of experimental technique to fabricate ultrathin polymer films via vacuum-vapor polymerization, investigation of electronic and optical properties polymers prepared via vacuum-vapor polymerization processes, were performed.The summary of the research results during FY of 1994 and 1995 are as follows.1.Based on our knowledge on the design of dyes and chromophores of EL materials, we designed new polymers which cpntain both charge transporting and emissive chromophores in their skeletons and syntheses of designed polymers were porformed. The EL devices made of the polymers thus synthesized were spin-coated into thin films useful for EL devices. EL performances of the polymer EL devices prepared via wet processes were compared wi … More th conventional EL devices made of vacuum-sublimed dye films. No distinct difference was found between the EL performances of polymer films and of dye films, and validity of our molecular design of polymers for EL devices were comfirmed.2.In the case of vacuum-sublimation polymerization, polycondensation reactions of two monomers on substrate must be used, and the examination of connecting groups which link chromophores is important. Linkage groups such as amide groups, ester groups, imide groups and urethane groups were tested and an urethane linkage was found to be the best among the groups tested.3.The vacuum-vapor polymerization technique was developed and applied for the preparation of thin polymer films for EL devices. It was found that the device performances were highly dependent on small amount of residual monomers, and detailed comparison of EL performances among different chromophores and connecting groups were difficult. Thus further impalements in experimental techniques of vapor-sublimation polymerization is found to be necessary. Less

该项目的最终目标是建立使用真空融合聚合技术制造电致（EL）设备的方法。关于适用于真空蒸气聚合的单体和聚合物设计的研究，通过真空蒸气聚合化制造超薄聚合物膜的实验技术的开发，通过真空和光学性质聚合物的研究通过真空和蒸气过程进行了研究。在EL材料的染料和发色团的设计上，我们设计了新的聚合物，这些聚合物在其骨骼中均具有电荷转运和发射的发色团和设计聚合物的合成。将如此合成的聚合物制成的EL设备旋转成可用于EL设备的薄膜。比较了通过湿工艺制备的聚合物EL设备的EL性能，以真空染料膜制成的更多常规EL设备进行了比较。在聚合物膜和染料膜的EL表演之间没有明显的差异，以及我们对EL设备的聚合物分子设计的有效性。2。在真空插入聚合物的情况下，必须使用两个单体对底物的多接头反应，并且必须使用链接组的相互连接组的链接成分很重要。测试了诸如酰胺组，酯组，酰亚胺基和氨基甲烷基等连锁组，并发现尿电烷连接是所测试的组中最好的。发现设备的性能高度依赖于少量残留单体，并且很难对不同发色团和连接组之间的EL性能进行详细比较。发现需要进一步的蒸气 - 融合聚合技术实验技术。较少的
