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.
