三芳胺类空穴传输材料结构与性能的关系

Relationship Between the Structure and Electrophotoconductive Properties of Triarylamines Hole Transport Materials

合成了一种苯二胺型三芳胺和5种联苯二胺型三芳胺化合物,通过对它们的紫外吸收光谱和光电性能数据的分析,系统地研究了三芳胺类化合物结构对其紫外吸收光谱和光电性能的影响。研究结果表明,三芳胺化合物的结构类型、取代基的性质、个数和位置对其光电性能均有不同程度的影响。当化合物中含有吸电基时空穴传输效率较高。

A phenylenediamine type and five biphenyldiamines type of triarylamine compounds were synthesized. The relationship among the structure, UV and electrophotoconductive properties was discussed through the testing data. The results indicated that the type of the triarylamine, the property, number and locality of the substitutes have influences on the transportation of the carriers. The electron withdrawing groups are in favor of the transportation.
