A platinum complex represented by the general formula 1, useful as a phosphorescence emission material, a tetradentate ligand useful for synthesizing the platinum complex, and a light-emitting device containing at least one of the platinum complex.
In the general formula 1, two of the rings A, B, C, and D each independently represent an aromatic ring or an aromatic heterocyclic ring, while the other two rings each represent a nitrogen-containing heterocyclic ring; R
A-D
represent the substituents; each the rings A and B, the rings B and C, and the rings C and D may be bound to each other to form a fused ring independently via the substituent R
A-D
; X
A-D
each represent a carbon atom or nitrogen atom; Q represents a bivalent atom or atomic group; Y represents a carbon or nitrogen atom; and n is an integer of 0 to 3.
一种以通用公式1表示的铂配合物,用作磷光发射材料,一种四齿配体,用于合成铂配合物,以及包含至少一种铂配合物的发光装置。在通用公式1中,环A、B、C和D中的两个分别表示芳香环或芳香杂环,而另外两个环分别表示含氮杂环;RA-D代表取代基;环A和B、环B和C、环C和D可以通过取代基RA-D独立地相互连接形成融合环;XA-D分别表示碳原子或氮原子;Q表示二价原子或原子团;Y表示碳或氮原子;n为0至3的整数。
