-Conjugated aromatic ring-containing compound and organic electroluminescent device

摘要

A pi-conjugated aromatic ring-containing compound represented by the formula (1) below is relatively stable and useful as a light-emitting material for light from blue-violet region to red region. [In the formula, R¹-R⁶ independently represent a hydrogen atom or the like; A and D independently represent a pyridine ring, pyrimidine ring, pyridazine ring, pyrazine ring, furan ring, pyrrole ring, pyrazole ring, imidazole ring, thiophene ring, benzothiadiazole ring, thieno[3,4-b]pyrazine ring, furo[3,4-b]pyrazine ring, 6H-pyrrolo[3,4-b]pyrazine ring or the like; a₁, a₂ and a₃ independently represent 0 or 1; and n₁ and n₂ independently represent an integer of 1-5.]
