Abstract
A triarylamine-based compound of formula 1, a method of preparing the same, and an organic light emitting device including the triarylamine-based compound of formula 1:where Ar1 through Ar4 are independently a substituted or unsubstituted C6-C30 aryl group or a substituted or unsubstituted C2-C30 heterocyclic group; R is a halogen atom, a cyano group, a substituted or unsubstituted C1-C30 alkyl group; n is an integer of 1 through 3; and m is an integer of 1 through 3. The triarylamine-based compound of formula 1 has excellent electrical properties and a great charge transporting capability. An organic light emitting device including an organic layer formed of the triarylamine-based compound has high efficiency, low operating voltage, great luminance, and long lifetime.
