A compound including a ligand L
1
of Formula I,
is described. In Formula I: rings A and B each independently represent a 5-membered or 6-membered carbocyclic or heterocyclic ring; X, Y, Z, and W are either carbon or nitrogen; R
1
to R
6
are selected from a variety of substituents, where adjacent substituents can be joined to form a fused ring; ligand L
1
is coordinated to a metal M by X-M and Y-M bonds; and ligand L
1
is optionally linked with other ligands to produce a tridentate, tetradentate, pentadentate or hexadentate ligand. Formulations and devices, such as an OLEDs, that include the compound that include a ligand L
1
of Formula I are also described.
描述了一种包括化合物的配体L1的化合物。在公式I中:环A和环B分别独立表示5元或6元碳环或杂环;X、Y、Z和W为碳或氮;R1至R6从各种取代基中选择,其中相邻的取代基可以连接形成融合环;配体L1通过X-M和Y-M键与金属M配位;配体L1还可选择与其他配体连接以产生三齿、四齿、五齿或六齿配体。还描述了包含配体L1的公式I的化合物的配方和器件,例如OLEDs。
