| abstract |
The present invention provides a substituted ethynyl gold-nitrogen containing heterocyclic carbene complex represented by the general formula (1): n n n n n n n n n n wherein L represents a nitrogen containing heterocyclic carbene ligand; and X represents an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group or a heterocyclic group; in which one or more hydrogen atoms on the carbon atom(s) of X may be replaced by a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, a dialkylamino group, an acyl group or an arylcarbonyl group; and, when more than one hydrogen atom on the carbon atom(s) of X is replaced by the alkyl group, the alkenyl group, the aryl group, the aralkyl group, the alkoxy group, the aryloxy group, the dialkylamino group, the acyl group or the arylcarbonyl group, the adjacent groups may be bonded together to form a ring,n na method for preparing the same, and an organic electroluminescent device comprising the substituted ethynyl gold-nitrogen containing heterocyclic carbene complex in at least one organic compound thin layer. |
