HEAVY METAL COMPLEX OF ETHYNYL GROUP-SUBSTITUTED FUSED HETEROCYCLIC COMPOUND, METHOD FOR PRODUCING SAME, SYNTHETIC INTERMEDIATE THEREOF, METHOD FOR PRODUCING SAME, AND ORGANIC ELECTROLUMINESCENT DEVICE

摘要

Disclosed is a heavy metal complex of an ethynyl group-substituted fused heterocyclic compound which is represented by the following formula (1) (wherein M represents a heavy metal element, L represents a monodentate ligand or bidentate ligand; Z represents a halogen atom, alkyl group, alkenyl group, aryl group, aralkyl group, alkoxy group, aryloxy group, nitro group, cyano group or dialkylamino group; n represents an integer of 0-6; Zs may be the same or different and when Zs are alkyl groups, alkenyl groups, aryl groups, aralkyl groups, alkoxy groups, aryloxy groups or dialkylamino groups, two adjacent groups may combine together to form a ring; A and B respectively represent CH or N, and when A or B is CH, the hydrogen atom may be substituted by Z or an ethynyl group; and k represents an integer of 1-4). Also disclosed are a method for producing the same, a synthetic intermediate thereof, a method for producing such a synthetic intermediate, and an organic electroluminescent device containing the same.
