【摘要】 基于联吡啶和1,4-二苯乙烯基苯的p-共轭电致发光材料的合成和性质研究 在有机电致发光器件的组成材料中,发光材料是必不可少的。本文设计并合成了3个基于联吡啶的新化合物,通过对其光电学性质和热力学性质的研究表明此类化合物荧光范围在450nm蓝光区,其中化合物1和3的热稳定性很好,通过TG-DTA测定分解温度在360℃以上,是令人满意的蓝光材料。 齐聚苯乙烯类化合物共轭链长度可以控制,在环上引入给电子基团和吸电子基团得到分子内电荷转移型材料。针对目前红光材料稀少本文在齐聚苯乙烯骨架上进行修饰引入氰基和不同长度的烷氧基合成了3个新的分子内电荷转移型红光材料。所合成的化合物中有2个是非晶态的,化合物4和6对热很稳定质量损失5%时温度在300℃以上而且荧光范围在590nm接近红光区,有望成为好的红色掺杂材料。

【Abstract】 Among the composition materials of OELD, light-emitting materials is essential. In this paper, three novel compounds based on bipyridine were designed and synthesized. By investigating the photoelectric and thermal properties, the results showed the luminescent range of compounds is 450nm blue light region. Compounds 1 and 3 exhibited remarkably thermal stability. The decomposition temperature of compounds 1 and 3 are at above 360℃ as determined by TG-DTA. So they might be potential candidates for blue light-emitting materials.The chain of OPV can be controlled. By introduction of electron-withdrawing groups and electron-donor groups in chain, the author obtains intra-molecular charge transfer materials. In this paper by chemical modification in OPV backbone, three novel intra-molecular charge transfer red materials were obtained to figure out the shortage of red light-emitting materials. There are two amorphous among synthesized compounds. Compounds 4 and 6 exhibited remarkably thermal stability and the temperature of 5% loss weight are above 300℃. Their luminescent range is at 590nm near red light region and will be desirable red doped materials.
