| abstract |
The present invention provides the following formula (1): In the formula, M represents a heavy metal element, L represents a monodentate ligand or a bidentate ligand, Z represents a halogen atom, an alkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group Represents a group, a nitro group, a cyano group, or a dialkylamino group, n is an integer of 0 to 6, and a plurality of Z may be the same or different, and Z is an alkyl group, an alkenyl group, an aryl group, In the case of an aralkyl group, an alkoxy group, an aryloxy group, or a dialkylamino group, these two adjacent groups may be bonded to form a ring, and A and B each represent CH or N, and A or B When is CH, the hydrogen atom may be substituted with Z or an ethynyl group, and k is an integer of 1 to 4. An ethynyl group-substituted fused heterocyclic compound heavy metal complex represented by formula (1), a production method thereof, a synthesis intermediate thereof and a production method thereof, and an organic electroluminescence device containing the same are disclosed. |
