Compound having benzotriazole ring structure and organic electroluminescent element

An organic electroluminescence device, comprising:

• a pair of electrodes;
• and
• at least one organic layer sandwiched therebetween,
• wherein the device comprises a compound having a benzotriazole ring structure represented by formula (1), as a constituent material of at least one organic layer:
• wherein
• 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;
• A and B are the same as or different from each other and each represent a hydrogen atom or a monovalent group of formula (2), provided that A and B are not simultaneously hydrogen atoms:
• wherein
• R1 to R8 are the same as or different from each other and each represent a hydrogen atom, a deuterium atom, a fluorine atom, a chlorine atom, a cyano group, a trifluoromethyl group, a linear alkyl group having 1 to 6 carbon atoms, a branched alkyl group having 3 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 is an integer of 1 or 2,
• X represents a carbon atom or a nitrogen atom,
• wherein when X is a nitrogen atom, the nitrogen atom does not have substituents or bonding groups of R1, R2, and R3, and there is no R4;
• and
• wherein when m is 2, a plurality of R1, R2, R3, and R4, and X each are the same or different.
