The present invention provides a substituted ethynyl gold-nitrogen containing heterocyclic carbene complex represented by the general formula (1):
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,
a 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.
本发明提供了一种置换的乙炔基金属-氮杂环卡宾配合物,其通式表示为(1):其中L代表含氮杂环卡宾配体;X代表烷基、环烷基、芳基、芳基烷基或杂环基;其中X的碳原子上的一个或多个氢原子可以被卤素原子、烷基、环烷基、烯基、芳基、芳基烷基、烷氧基、芳氧基、二烷基氨基、酰基或芳基羰基所取代;当X的碳原子上有多个氢原子被烷基、烯基、芳基、芳基烷基、烷氧基、芳氧基、二烷基氨基、酰基或芳基羰基所取代时,相邻的基团可以结合形成环;本发明还提供了一种制备该配合物的方法,以及包含该置换的乙炔基金属-氮杂环卡宾配合物的至少一个有机化合物薄层的有机电致发光器件。
