Organic electroluminescence device

An organic electroluminescence device which comprises an organic layer disposed between at least one pair of electrodes, wherein the organic layer comprises a metal complex of quinoline and a compound selected from compounds represented by the following general formulae [1] to [14] and [16] to [18]:

• wherein X1 to X20 each independently represents 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 groups having 8 to 30 carbon atoms;
• a pair of adjacent groups represented by X1 to X20 and a pair of adjacent substituents to groups represented by X1 to X20 may form a cyclic structure in combination;
• when a pair of adjacent substituents are aryl groups, the pair of substituents may be a single group;
• and at least one of substituents represented by X1 to Xi, i representing a number of 12 to 20, comprises an amine group or an alkenyl group;
• wherein R1 to R4 each independently represent an alkyl group having 1 to 20 carbon atoms or a substituted or unsubstituted aryl group having 6 to 30 carbon atoms;
• in one or both of a pair of groups represented by R1 and R2 and a pair of groups represented by R3 and R4, the groups forming the pair may be bonded through —O— or —S—;
• R5 to R16 represents 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 groups having 8 to 30 carbon atoms;
• a pair of adjacent groups represented by R5 to R16 and a pair of adjacent substituents to groups represented by R5 to R16 may form a cyclic structure in combination;
• and at least one of substituents represented by R5 to R16 comprises an amine group or an alkenyl group.
