Polymeric compounds, 1,4-phenylenediamine derivatives, the charge-transporting material, an organic electroluminescence element material and organic electroluminescence device

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent element drivable at a low voltage and in high luminous efficiency, having good heat resistance and capable of keeping stable luminous characteristics over a long period, in which defect causing short circuit in preparation of an element result from surface roughness of an anode is prevented.;SOLUTION: In the organic electroluminescent element, a hole-injecting layer 3 containing a polymer compound having a recurring unit represented by formula (I) and an electron-accepting compound is provided.;COPYRIGHT: (C)2004,JPO
