ORGANIC COMPOUND, CHARGE TRANSPORT MATERIAL, ORGANIC ELECTROLUMINESCENT ELEMENT MATERIAL, AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a compound that has high a solubility, an amorphous property and a suitable charge transportability, and to provide an organic electroluminescent element using the same. SOLUTION: The organic compound is represented by general formula(I)[wherein the ring A denotes an optional aromatic ring, n denotes an integer of 3 or more and wherein the ring A has a - NR1R2substituent ( provided that each of R1and R2independently denotes an optional substituent or jointly forms a cyclic amino group which may have a substituent group) at the neighbored three or more- substituted positions, one or more substituted position has no substituent or is unsubstituted with an optionally different group from the -NR1R2group, and the number of n of -NR1R2groups in one molecule may be the same or different].
