Hole Transporting Materials

Two hole-transporting materials containing triphenylamine unit, 4-(4-(di-p- tolylamino)styryl)-N,N-di-p-tolylbenzenamine (TM 1) and 4-(4-(4-(di-p-tolylamino)styryl) styryl)-N,N-di-p-tolylbenzenamine(TM 2), have been designed and synthesized in this paper, which using conjugated bonds as the bridge to connect two molecules of triphenylamine. The optical spectrum, thermo-stabilization and electrochemical properties of two compounds were studied. The results show that these compounds have blue emission, proper HOMO levels and high thermal stability. Furthermore, EL devices with the configuration of ITO/HTL/Alq3/Al show the activating voltages are 11V for TM 1 and 5.5V for TM 2, respectively. The maximal luminancce efficiencies are 1.135cd/A for TM 1 and 2.068cd/A for TM 2, respectively. The difference of EL performance indicates that TM 2 possessing better hole-transporting performance than that of TM 1.
