Arylamine compounds containing arylpyridine groups and application of arylamine compounds containing arylpyridine group

The invention relates to compounds with the general formula (1) shown in the specifications. Ar1, Ar2 and Ar3 are substituent groups, wherein at least one group is an aromatic group which contains a pyridine ring and has 5 to 60 carbon atoms, and the residual groups are independently selected from hydrogen atoms, alkane with 1 to 40 carbon atoms, an aromatic group with 5 to 50 carbon atoms and a nitrogen-containing heterocycle with 5 to 50 carbon atoms; and n in the aromatic group is 1 or 2. The invention also provides application of the compounds to organic electroluminescent devices, particularly use of the compounds as matrix materials of phosphorescent dopants in electrophosphorescent devices or electron transport materials.
