Abstract:
An organic light-emitting device material comprising at least one compound represented by formula (I) or a precursor thereof: wherein R1 to R7 each independently represents hydrogen atom, a halogen atom, a cyano group, a formyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted primary amino group, a substituted or unsubstituted secondary amino group, a substituted or unsubstituted tertiary amino group, a substituted or unsubstituted imino group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted carbonamido group, a substituted or unsubstituted sulfonamido group, a substituted or unsubstituted carbamoyl group, a substituted or unsubstituted sulfamoyl group, a substituted or unsubstituted alkylcarbonyl group, a substituted or unsubstituted arylcarbonyl group, a substituted or unsubstituted alkyl-sulfonyl group, a substituted or unsubstituted arylsulfonyl group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted aryloxycarbonyl group, a substituted or unsubstituted alkylcarbonyloxy group, a substituted or unsubstituted arylcarbonyloxy group, a substituted or unsubstituted urethane group, a substituted or unsubstituted ureido group or a substituted or unsubstituted carboxylic acid ester group, two or more groups selected from R1 to R7 may combine with each other to form an aliphatic carbon ring, an aromatic carbon ring, a non-aromatic heterocyclic ring or an aromatic heterocyclic ring and R4 may further represent R8 and R9 each represents hydrogen atom, an alkyl group, an aryl group or a heterocyclic group, R8 and R9 may combine with each other to form a cyclic structure or may form a polymer compound having the structure represented by formula (I) in a part of the repeating unit thereof and R1 or R3 in the structure represented by formula (I) and may combine to form a trimer compound, and R represents hydrogen atom, an alkyl group, an aryl group or a heterocyclic group.
