Compounds comprising phosphorus-containing metal complexes can be used in electroluminescent devices and have an emission maximum closer to the blue region of the visible light spectrum. The complexes can be used within an organic active layer in electronic devices, such as displays, detectors, voltaic cells, solid-state lighting, illumination devices or the like. The complexes may also be used as catalysts or as indicators in other applications. The new compounds can be used without the need of a host material. In non-limiting embodiments, Pt or Ir may be used for the metal atom within the complex, one ligand may include a phosphorus-containing bidentate ligand, and another ligand may include a monoanionic bidentate ligand. The phosphorus-containing bidentate ligand may include a benzyl group, a phenoxy group, a phenylamino group, or the like.
由含磷金属络合物组成的化合物可用于电致发光装置,其发射最大值更接近可见光光谱的蓝色区域。这些配合物可用于电子设备中的有机活性层,如显示器、探测器、伏特电池、固态照明、照明设备等。这些复合物还可用作催化剂或其他应用中的指示剂。新化合物的使用无需宿主材料。在非限制性实施例中,铂或铱可用于配合物中的金属原子,一种配体可包括含磷双齿配体,另一种配体可包括单阴离子双齿配体。含磷双齿配体可包括苄基、苯氧基、苯胺基等。
