Abstract:
An organic electroluminescent device comprising one or more organic thin film layer(s) placed between an anode and a cathode, at least one of said organic thin film layer(s) being a luminescent layer,wherein said luminescent layer comprises a compound represented by the following general formula [2.1]: wherein Ar1 represents a substituted or unsubstituted arylene group having 5 to 42 carbon atoms; Ar2 and Ar4 independently represent a group represented by the following general formula [2.2]; Ar3 and Ar5 independently represent an aryl group having 6 to 20 carbon atoms except for having styryl group; and Ar3 and Ar5 have at least one saturated hydrocarbon group having 2 or more carbon atoms in which oxygen atom(s) may be inserted, at a position ortho to a carbon atom bonded to a nitrogen atom of said general formula [2.1]; and Ar2 and Ar3 and/or Ar4 and Ar5 may mutually bond to form a ring: wherein, each of R1 to R5 and R7 to R11 independently represents a hydrogen atom, halogen atom, hydroxy group, substituted or unsubstituted amino group, cyano group, nitro group, substituted or unsubstituted alkyl group, substituted or unsubstituted alkenyl group, substituted or unsubstituted cycloalkyl group, substituted or unsubstituted alkoxy group, substituted or unsubstituted aromatic hydrocarbon group, substituted or unsubstituted aromatic heterocyclic group, substituted or unsubstituted aralkyl group, substituted or unsubstituted aryloxy group, substituted or unsubstituted alkoxycarbonyl group, or carboxyl group; R6 represents a halogen atom, hydroxy group, substituted or unsubstituted amino group, cyano group, nitro group, substituted or unsubstituted alkyl group, substituted or unsubstituted alkenyl group, substituted or unsubstituted cycloalkyl group, substituted or unsubstituted alkoxy group, substituted or unsubstituted aromatic hydrocarbon group, substituted or unsubstituted aromatic heterocyclic group, substituted or unsubstituted aralkyl group, substituted or unsubstituted aryloxy group, substituted or unsubstituted alkoxycarbonyl group, or carboxyl group; and two of R1 to R11 may form a ring.
