项目摘要

For the purpose of developing organic display devices with high performances, we have investigated the synthesis and electrochromic properties of new polymers containing pendant oligothiophenes, and fabrication and performances of organic electroluminescent (EL) devices using novel amorphous molecular materials.We have synthesized new vinyl and methacrylate homopolymers containing pendant oligothiophenes with well-defined structures and new methacrylate copolymers containing pendant terthiophene and oligoethyleneoxide moieties. These polymers were found to constitute a novel class of potential electrochromic materials, undergoing a reversible clear color change on electrochemical doping and dedoping. It was also found that the response times for coloration and decoloration improve for the methacrylate copolymers are than for the methacrylate homopolymer.We have designed and synthesized novel pi-electron starburst molecules with high glass-transition temperatures, and developed thermally stable organic EL devices using these novel amorphous molecular materials. In addition, we have developed a novel blue-emitting meterial, tri(p-terphenyl-4-yl) amine, and blue-emitting organic EL devices. We found that the emission color can be tuned by using exciplex formation for a fixed electron-transport material in combination with holetransport materials with varying ionization potentials. We have designed and synthesized a novel family of pi-conjugated molecules containing an oligothiophene moiety and found that the electroluminescence color can be controlled by varying the conjugation length of the oligothiophene moiety.

为了开发具有较高性能的有机展示设备，我们研究了含有doligophiophiophenes的新聚合物的合成和电致色素，以及使用新型的无界分子材料的有机电发光（EL）设备的制造和性能。结构和新的甲基丙烯酸酯共聚物，其中含有垂thiphiephene和抗乙基氧化物部分。发现这些聚合物构成了一类新型的潜在电致色素材料，在电化学掺杂和depoping上经历了可逆的透明颜色变化。还发现，甲基丙烯酸酯共聚物的着色和脱色的响应时间比甲基丙烯酸酯均聚物物相比，我们已经设计和合成了具有高玻璃透射温度的新型Pi-Electron Starburst分子，并使用这些新型的稳定的有机EL设备，使用这些新型的有机器件，使用这些新型的有机器件。此外，我们开发了一种新型的蓝色发射仪表，Tri（P-二苯基-4-基）胺和蓝色发射有机EL设备。我们发现，可以通过使用固定电子传输材料与具有不同电离电势的Holetransport材料结合使用固定电子传输材料来调整发射颜色。我们设计并合成了一个新型的含有寡噻吩部分的Pi偶联分子家族，发现可以通过改变寡噻吩部分的共轭长度来控制电致发光颜色。
