系统研究了系列不同共轭与非共轭水/醇溶聚合物作为界面修饰材料在聚合物发光二极管和聚合物太阳电池中的应用及结构性能关系.研究了界面层厚度,器件金属电极功函对材料界面修饰性能的影响.在此基础上,系统对比研究了共轭与非共轭水/醇溶聚合物界面材料在不同聚合物光电器件中界面修饰性能的差别.内建电势测试与器件研究结果表明,在聚合物发光二极管中,共轭材料表现出明显优于非共轭材料的性能,特别是在超高功函数的金属金电极器件中,共轭的水/醇溶聚合物材料依然表现出很好的电子注入/传输性能;在聚合物太阳电池中,共轭材料的界面修饰性能也优于非共轭类界面修饰材料.
The relationship between structure and properties of a series of conjugated and non-conjugated water / alcohol-soluble polymers as interfacial modified materials in polymer light-emitting diodes and polymer solar cells was systematically investigated. The effects of interfacial layer thickness, work function On the interface modification properties of materials.On the basis of this, the difference between the interface modification properties of conjugated polymer and non-conjugated water / alcohol-soluble polymer interfacial materials in different polymer photoelectric devices was comparatively studied systematically.The built-in potential test and device The results show that in polymer light-emitting diodes, conjugated materials show significantly better performance than non-conjugated materials, especially in ultra-high work function metal-gold electrode devices. Conjugated water / alcohol-soluble polymer materials Still showed good electron injection / transport properties; in polymer solar cells, the interfacial properties of the conjugated materials were also better than the non-conjugated interfacial materials.
