Document Type and Number:
Japanese Patent JP5751727
Kind Code:
B2
Abstract:
Objects of the invention are to provide an organic compound having excellent properties, which is excellent in electron-injecting/transporting performance, has hole-blocking ability, and is highly stable in a thin-film state, as a material for an organic electroluminescent devices having a high-efficiency and a high durability; and to provide an organic electroluminescent device having a high-efficiency and a high durability using the compound. The invention relates to: a compound having a pyridoindole ring structure bonded with a substituted pyridyl group, which is represented by the following general formula (1); and an organic electroluminescent device comprising a pair of electrodes and at least one organic layer interposed between the electrodes, wherein the at least one organic layer contains the compound.
in which Ar represents a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; R 1 to R 3 may be the same or different and represent a hydrogen atom, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; R 4 to R 11 may be the same or different and represent a hydrogen atom, a fluorine atom, a chlorine atom, a cyano group, a trifluoromethyl group, a linear or branched alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; m and n represent an integer of 1 to 3; and W, X, Y, and Z represent a carbon atom or a nitrogen atom, provided that the case where R 1 to R 3 in the molecule are simultaneously all hydrogen atoms is excluded, and that only one of W, X, Y, and Z is a nitrogen atom and the nitrogen atom does not have the substituent of R 8 , R 9 , R 10 , or R 11 .
