Nitrogen-containing heterocyclic derivative, material for organic electroluminescence device using the same, organic electroluminescent element and electronic device using the same

摘要

A nitrogen-containing heterocyclic derivative represented by the following formula (1) in which an indole structure is bonded to a benzophenanthrene ring, a material for an organic electroluminescence device using the nitrogen-containing heterocyclic derivative, and an organic electroluminescence device and an electronic device using the material , And a novel material useful as an organic electroluminescence device material.[In the formula (1), R₁~ R₁₂Each independently represent a hydrogen atom or a substituent, and R₁~ R₁₂May be bonded to each other to form a saturated or unsaturated divalent group which forms a ring. However, R₁~ R₁₂Are bonded to each other to form a ring structure represented by the following formula (a).R₁₃~ R₁₇Each independently represent a hydrogen atom or a substituent, and R₁₃~ R₁₇May be bonded to each other to form a saturated or unsaturated divalent group which forms a ring. ]
