Document Type and Number:
WIPO Patent Application WO/2013/157367
Kind Code:
A1
Abstract:
A triphenylene derivative according to the present invention is represented by general formula (1) (wherein Ar1 and Ar2 independently represent an aromatic group). The compound has such a structure that an aromatic tertiary amine is introduced into a triphenylene ring. Therefore, the compound has the properties (A) to (E) mentioned below which are associated with the structure, and is useful as a hole-transporting substance to be used in an organic EL element: (A) the hole injection property is good; (B) the hole mobility is high; (C) the electron stopping ability is excellent; (D) the state is stable when formed into a thin film; and (E) the heat resistance is excellent.
