TRITYL COMPOUND, METHOD FOR PRODUCING TRITYL COMPOUND, CHARGE-TRANSPORT MATERIAL, LUMINESCENT MATERIAL AND ORGANIC ELECTROLUMINESCENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent device of a long life and high luminous efficiency derived from a phosphorescent compound. SOLUTION: The organic electroluminescent device has a trityl compound represented by general formula (I) as a luminescent material (wherein, A indicates a nitrogen that may have a substituent or an oxygen atom; R1and R2each independently indicates a hydrogen atom or an optional substituent, provided that both or either of R1and R2indicates a trityl group that may have a substituent).
