In the results of the optical properties, these molecular monomers have different HOMO and LUMO energy gap such that there are dual-emission and energy transfer mechanism in solution fluorescence spectrum. In the study of the electrochemical properties, various of triphenylamine derivaties have different oxygen binding site and they make elecropolymerization happen or not. In the applications of the hole-transport materials, the performance of compound 21 is better than other compounds. The electropolymerized-film may have residual cation molecules so they can increase the concentration of hole-transport. Due to this reason , compound 21 is suitable to become hole-transport materials.

在光学研究方面，由於目标化合物内单体的HOMO及LUMO能阶差异，使得在溶液萤光放射上有双发射及能量转移的情形发生；在电化学研究方面，不同的三苯胺衍生物由於氧基的位置不同，使得取代基在间位的化合物有不错的电聚合效果；而元件的应用上，具有咔唑基团的化合物21由於在形成电聚薄膜后，可能有残余的阳离子态化合物，使得电聚薄膜内的电洞数浓度较高，因此与其他元件相比之下，有较低的启动电压和不错的元件效率。
