测定了苯撑乙烯齐聚物、吡唑啉衍生物、钌配合物、铼配合物以及常用的有机染料与载流子传输材料等一百余种有机 (包括有机小分子 ,配合物和聚合物 )材料的能带结构参数 ,探讨了不同取代基对材料“能带”结构的影响。基于能带匹配的原则 ,同时考虑载流子迁移率匹配及各有机层间的厚度匹配 ,设计了不同结构的电致发光器件。研究表明 ,能带匹配、迁移率匹配以及厚度匹配是提高有机电致发光器件性能的重要依据。
The results showed that more than one hundred kinds of organic (including organic small molecules, complexes and polymers), such as phenylene vinylene oligomers, pyrazoline derivatives, ruthenium complexes and rhenium complexes, as well as common organic dyes and carrier transport materials, ) Materials, the effects of different substituents on the “band” structure of materials were discussed. Based on the principle of band matching and considering the carrier mobility matching and the thickness matching between organic layers, different structures of electroluminescent devices are designed. The research shows that band matching, mobility matching and thickness matching are the important basis to improve the performance of organic electroluminescent devices.
