Substituted ethynyl gold-nitrogen containing heterocyclic carbene complex and organic electroluminescent device using the same

Abstract

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