Abstract:
1. An organic electroluminescent element comprising at least one pair of electrodes comprising an anode and a cathode, at least one of which having light permeability, and one or a plurality of organic compound layers held between the electrodes, wherein at least one organic compound layer contains at least one kind of charge-transferable polyether comprising a repetition unit containing at least one partial structure selected from the group consisting of the following general formulae (I-1) and (I-2): wherein Ar represents one selected from the group consisting of a monovalent benzene ring, a monovalent polynuclear aromatic hydrocarbon, a monovalent condensed aromatic hydrocarbon and a monovalent hetero ring, X represents one selected from the group consisting of a divalent condensed aromatic hydrocarbon, a divalent polynuclear hetero group hydrocarbon, a divalent hetero ring-containing polynuclear aromatic hydrocarbon and a divalent hetero ring-containing condensed aromatic hydrocarbon, T represents a divalent straight-chain hydrocarbon group having 6 to 18 carbon atoms, a divalent unsaturated straight-chain hydrocarbon group having 2 to 5 carbon atoms, or a divalent branched hydrocarbon group having 2 to 30 carbon atoms, m denotes an integer of 0, and k denotes 0 or 1.
