PURPOSE: A tertiary arylamine is provided to have economic synthesis process, to have excellent hole transfer and electron transfer ability by an asymmetric structure, to lower the generation of crystalline, and to improve the lifetime of a device. CONSTITUTION: A tertiary arylamine is represented by chemical formula 1. In chemical formula 1, each of Ar1 and Ar2 is C4-25 arylene and C4-25 heteroarylene; each of a1 and a2 is selected from H, C4-25 aryl group, C4-25 heteroaryl and C4-25 heteroarylene; each of a1 and a2 is selected from H, C4-25 aryl group, C4-25 heteroaryl, amino, and substituted amino group; Y is C or N; a3 is an unshared electron pair when Y is N; a4 is selected from H, C1-13 alkyl group, C4-25 aryl group, and C4-25 heteroaryl group; if Y is C, each of a3 and a4 is selected from H, C1-13 alkyl group, C4-25 aryl group, and C4-25 heteroaryl group, or a structure connected by a C4-20 ring. |
