Multidentate metal complexes useful as phosphorescent emitters in display and lighting applications have the structures as described herein. Multidentate metal complexes and compositions including one or more of the complexes described herein can be useful as emitters in organic light emitting diodes (OLEDs ), displays and lighting applications, and photovoltaic devices. Generally, a chemical structural change will affect the electronic structure of the compounds, which thereby affects the optical properties of the compounds (e.g., emission and absorption spectra). Thus, the compounds described herein can be tailored or tuned to a particular emission or absorption energy. In some aspects, the optical properties of the compounds disclosed herein can be tuned by varying the structure of the ligand surrounding the metal center.
多齿金属配合物可作为磷光发射器在显示和照明应用中使用,具有如本文所述的结构。 包括本文所述的一个或多个配合物的多齿金属配合物和组合物可作为有机发光二极管(OLEDs)、显示器和照明应用以及光伏器件中的发射器。 通常,化学结构的变化会影响化合物的电子结构,从而影响化合物的光学性质(例如,发射和吸收光谱)。 因此,本文描述的化合物可以被定制或调整到特定的发射或吸收能量。 在某些方面,通过改变环绕金属中心的配体结构可以调整本文披露的化合物的光学性质。
