Abstract
An organic electroluminescent device having a pair of electrodes and at least one organic layer including a light-emitting layer interposed between the pair of electrodes, in which the organic layer contains at least one platinum complex compound having a quadridentate ligand containing a partial structure represented by formula (I): wherein Z1 represents a nitrogen-containing heterocycle coordinated to the platinum through a nitrogen atom; L1 represents a single bond or a linking group; R1, R3 and R4 each independently represent a hydrogen atom or a substituent; and R2 represents a substituent.
Claims2
A compound represented by the formula (V):
- wherein L1, L2 and L3 each independently represent a single bond or a linking group;
- R1, R3, R4, R5, R7 and R8 each independently represent a hydrogen atom or a substituent;
- wherein R2 and R6 each independently represent an alkyl group, an aryl group, an amino group, an aryloxy group, a heterocyclic oxy group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an alkylthio group, an arylthio group, a heterocyclicthio group, a sulfonyl group, a halogen group, a cyano group, a heterocyclic group, a silyl group or a silyloxy group;
- Ra and Rb each independently represent a hydrogen atom, an alkyl group, an aryl group, an amino group, an alkoxy group or a fluorine atom;
- and n and m each independently represent an integer of from 0 to 3.
