Thieno[3,2-b]pyrrole is an effective nonconventional semiconducting building block that could be generated in gram quantities with relatively high overall yields. Three organic semiconductors containing thieno[3,2-b]pyrrole were synthesized in good yields without requiring time-consuming column purifications. The synthesis, optical and electrochemical properties were systematically investigated.1 Introduction2 Experimental3 Synthesis and Characterization4 Theoretical Calculations5 Optical and Electrochemical Properties6 Thermal Stability7 Fluorescence Experiments8 GIXRD Data9 Conclusions

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.
