COMPOUND HAVING TRIAZOLE RING STRUCTURE SUBSTITUTED WITH PYRIDYL GROUP AND ORGANIC ELECTROLUMINESCENT DEVICE

摘要

An object of the invention is to provide an organic compound having excellent electron transport property and hole blocking property as a material for a highly efficient organic EL device, and also provide a highly efficient organic EL device using the compound. This invention relates to a compound having a tria.zole ring structure to which a substituted pyridyl group is bonded, represented by the following general formula (1), and to an organic electroluminescence device comprising the compound:
wherein Ar 1 and Ar 2 may be the same or different and each represents a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; any one of R 1 , R 2 , R 3 , R 4 , and R 5 is a bonding group and the rest thereof may be the same or different and each represents a hydrogen atom, a fluorine atom, a cyano group, an alkyl group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; any two of R 6 , R 7 , R 8 , R 9 , and R 10 are bonding groups and the rest thereof may be the same or different and each represents a hydrogen atom, a fluorine atom, a cyano group, an alkyl group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; and m represents an integer of 1 to 4.
