CARBAZOLE COMPOUND WITH SUBSTITUENT GROUP CONTAINING ELECTRON-ACCEPTING NITROGEN CONTAINING HETEROARYL AND ORGANIC ELECTROLUMINESCENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent device which improves the lifetime of an electroluminescent element and a drive voltage.SOLUTION: A carbazole compound with a substituent group containing an electron-accepting nitrogen containing heteroaryl is used as an electron transfer material, thereby manufacturing an organic electroluminescent device.
