Organic electroluminescence device
Abstract:
An organic electroluminescence device includes an organic layer disposed between at least one pair of electrodes, wherein the organic layer includes at least one fluorescent compound selected from compounds represented by the following general formulae (1) and (2): wherein X1 to X16 each independently represents a hydrogen atom, a linear, branched or cyclic alkyl group having 1 to 20 carbon atoms, a linear, branched or cyclic alkoxy group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 30 carbon groups, a substituted or unsubstituted arylamino group having 6 to 30 carbon atoms, a substituted or unsubstituted alkylamino group having 1 to 30 carbon atoms, a substituted or unsubstituted arylalkylamino group having 7 to 30 carbon atoms or a substituted or unsubstituted alkenyl group having 8 to 30 carbon atoms; a pair of adjacent groups represented by X1 to X2 and a pair of adjacent substituents to groups represented by X1 to X2 may form a cyclic structure in combination; a pair of adjacent groups represented by X3 to X16 and a pair of adjacent substituents to groups represented by X3 to X16 may form a cyclic structure in combination; when the pair of adjacent substituents are aryl groups, the pair of substituents may be a single group; and in the formulae at least one of the substituents of X3 to X14 or X16 includes amino group.
