Abstract
Four structural asymmetric triarylamines were synthesized by diarylamines and 3,5-dimethyl-iodobenzene as the starting materials using Ullmann reaction. They are new compounds except the compound 1. The structures of the target com- pounds were characterized by IR, 1 H NMR, 13 C NMR, HRMS and elemental analysis. The optical, electrochemical, and ther- mal properties were examined. The results indicated that the synthesized compounds emitted green fluorescence in chloro- form, and exhibited a good electrochemical and thermal stability. The synthesized triarylamines are potential hole-transporting materials and green-light-emitting materials.
