Claims13
An arylamine compound represented by Formula 1:
- where X is a carbon atom, a nitrogen atom, or a sulfur atom,
- n is 1,
- Y is an oxygen atom or a sulfur atom, wherein, when Y is an oxygen atom, 1, 2, 3, 4, 5, 6, 7, 8, and 9 represent bonding positions on a dibenzofuranyl group formed thereby, and when Y is a sulfur atom, 1, 2, 3, 4, 5, 6, 7, 8, and 9 represent bonding positions on a dibenzothiophenyl group formed thereby,
- each R is independently a hydrogen atom, a deuterium atom, a fluorine atom, a chlorine atom, a cyano group, a trifluoromethyl group, a nitro group, a substitutable straight-chain or branched-chain alkyl group having 1 to 6 carbon atoms, a substitutable cycloalkyl group having 5 to 20 carbon atoms, a substitutable straight-chain or branched-chain alkenyl group having 2 to 6 carbon atoms, a substitutable straight-chain or branched-chain alkyloxy group having 1 to 6 carbon atoms, a substitutable cycloalkyloxy group having 5 to 20 carbon atoms, a substituent or non-substituent aromatic hydrocarbon group, a substituent or non-substituent aromatic hetero ring group, a substituent or non-substituent condensed multi-ring aromatic group, or a substituent or non-substituent aryloxy group, and in which monovalent, bivalent or adjacent two substituents may have a ring structure.
