    • A platinum (II) complex of the general formula (I) or (II), in which Ar1, Ar2, and Ar3 are each independently aryl, heteroaryl, or heterocyclic. Ar1, Ar2, and Ar3 together form a tridentate ligand coordinated to the platinum through atoms X, Y, and Z, respectively, and X, Y, and Z are independently carbon or nitrogen. V is a bridging group or a covalent bond, and W is an anion. In general formula (I) in some cases, Ar1 is an anion and Ar2 and Ar3 are neutral; in other cases, Ar1 and Ar3 are neutral and Ar2 is an anion. In general formula (II), in some cases, Ar3 is an anion and Ar1 and Ar2 are neutral; in other cases, Ar1 and Ar3 are neutral and Ar2 is an anion. The complexes are asymmetric. The complexes emit in the UV to near IR range and are useful as emitters for organic light emitting devices.
    • 通式(I)或(II)的铂(II)络合物,其中Ar 1,Ar 2和Ar 3各自独立地为芳基,杂芳基或杂环。 Ar1,Ar2和Ar3分别一起形成通过原子X,Y和Z与铂配位的三齿配体,X,Y和Z独立地为碳或氮。 V是桥连基团或共价键,W是阴离子。 通式(I)在某些情况下,Ar 1为阴离子,Ar 2和Ar 3为中性; 在其它情况下,Ar1和Ar3是中性的,Ar2是阴离子。 在通式(II)中,在一些情况下,Ar 3是阴离子,Ar 1和Ar 2是中性的; 在其它情况下,Ar1和Ar3是中性的,Ar2是阴离子。 络合物是不对称的。 复合物在UV中发射到近红外范围,并且可用作有机发光器件的发射体。
