Abstract:
1. The organic electroluminescent device that comprises a pair of electrodes, and a plurality of organic layers sandwiched between the pair of electrodes, the organic electroluminescent device further including a light emitting layer that contains a phosphorescent light-emitting material and is sandwiched between the pair of electrodes, wherein the arylamine compound of the general formula (2) is used as a constituent material of at least one organic layer, wherein the arylamine compound of general formula (2) is an arylamine compound having four triphenylamine structures within the molecule, the four triphenylamine structures being connected by a single bond, or by a divalent group that does not contain a heteroatom, wherein R56 to R109 may be the same or different, and represent a hydrogen atom, a deuterium atom, a fluorine atom, a chlorine atom, cyano, trifluoromethyl, nitro, linear or branched alkyl of 1 to 6 carbon atoms that may have a substituent, cycloalkyl of 5 to 10 carbon atoms that may have a substituent, linear or branched alkenyl of 2 to 6 carbon atoms that may have a substituent, linear or branched alkyloxy of 1 to 6 carbon atoms that may have a substituent, cycloalkyloxy of 5 to 10 carbon atoms that may have a substituent, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, a substituted or unsubstituted condensed polycyclic aromatic group, or substituted or unsubstituted aryloxy, which may bind to each other to form a ring, where at least one of R56 to R109 is a deuterium atom, or a substituent that contains a deuterium atom, and wherein A2 represents the divalent group of the following structural formulae (B) to (F), wherein R29 to R32 may be the same or different, and represent a hydrogen atom or a deuterium atom, wherein R33 to R42 may be the same or different, and represent a hydrogen atom or a deuterium atom, wherein R43 to R50 may be the same or different, and represent a hydrogen atom or a deuterium atom, wherein R51 to R55 may be the same or different, and represent a hydrogen atom or a deuterium atom.
