中文摘要: 本项目在基于分子设计的基础上拟合成一系列含烷氧基、苯氧基取代的二溴代三苯胺衍生物,用这些二溴代三苯胺衍生物与9,9-二辛基芴通过钯催化Suzuki偶合反应合成了一系列三苯胺-芴有机共聚物;在共聚物的主链上引入了芳醚和电子传输基团磺酰基,采用量子理论方法研究三苯胺、三苯胺-芴有机共聚物的基态和激发态结构,计算其亲和能、电离能和电子发射等信息,从理论上阐明三苯胺-芴有机共聚物的结构与发光性能的关系。利用现代分析测试手段研究这类三苯胺-芴有机共聚物膜材料的光电转换性能包括空穴传输性能、电子传输性能、电致发光及发光稳定性。重点研究三苯胺上连接烷氧基、苯氧基数量与位置的差异对提高三苯胺上N阳离子自由基(空穴)的稳定性,进而提高三苯胺芴有机共聚物电致发光稳定性的作用规律。

英文摘要: Based on the molecular design strategies, we plan to synthetize a series of dibromo substituted triphenylamine derivatives by varying alkoxyl groups(phenoxyl group)substitution position and number. A series of conjugated triphenylamine-fluorene copolymers derived from 9,9-octylfluorene and dibromo substituted triphenylamine derivatives were prepared by the palladium-catalyzed Suzuki coupling reaction. Introducing phenoxyl and sulfonyl group with electron transporting ability in the copolymer main chain.Study on the ground and excited state structure of triphenylamine, triphenylamine-fluorene copolymers with the quantum theory methods; calculating their affinity energies, ionization energy and electron emission information; illustrating the relationship between copolymer structure and luminescent property form theory. We systematically investigate the photoelectric properties of triphenylamine-fluorene copolymers including hole transporting, photoluminescent properties and luminescence stability. We mainly discuss the photoelectric properties influence law of the different alkoxyl, phenoxyl) groups number and location on triphenylamine-fluorene organic copolymers.
