Electroluminescent materials based on the fluoranthene core and containing triarylamine segments were synthesized and characterized by IR, NMR, UV-Vis, and emission spectroscopic, electrochemical, and thermal studies. The electronic absorption and emission characteristics of the new functional materials were affected by the nature of the chromophore present on the fluoranthene nucleus. Incorporation of
基于电致发光材料 荧蒽合成了含有三芳基胺链段的核并通过IR,NMR,UV-Vis和发射光谱,电化学和热学研究对其进行了表征。新功能材料的电子吸收和发射特性受到荧蒽原子团上发色团性质的影响。胺官能团红的引入显着地改变了吸收和发射曲线,而对于氰基取代基则出现了边缘的红移。染料的氧化还原倾向也因取代基的性质而改变。给电子的氨基具有容易的氧化作用,而吸电子的氰基单元具有还原能力。分解温度(Ť d)观察到的染料异常高(406–527°C)。包含两种胺的电致发光器件,N-(4-叔丁基苯基)-N-(萘-1-基)-7,8,9,10-四苯基芴-3-胺(7c)和N-苯基-N-(7,8,9,10-四苯基荧蒽-3-基)py-1-胺(7d),配置为ITO / 7c或7d(40 nm)/TPBI或Alq 3(40 nm)/锂离子电池 (1纳米)/铝 (150nm)被制造并显示出源自染料的亮绿色的黄色发射。
