| Abstract: | A series of triarylamine derivatives, which can be used as hole transport materials, have been prepared by Ullmann coupling of diarylamines and aryl iodide, catalyzed by cuprous chloride and 1,10-phenanthroline. Their structures and thermal properties were characterized by NMR, IR, MS and DSC. The HOMO energy levels of these compounds were obtained from cyclic voltammetry, based on the values of -4.8 V for ferrocene (Fc) with respect to zero vacuum level. The LUMO energy levels were obtained from the HOMO energy levels together with the UV spetra. |
