More Information
Summary:The invention relates to an iridium complex taking a nitrogen heterocyclic carbenes as a second primary ligand and provided with a novel complexing mode. The molecules of the like iridium complex contain two same or different pyridine derivatives or isoquinoline derivatives as a first primary ligand and the nitrogen heterocyclic carbenes as the second primary ligand. Compared with the existing iridium complex which has been widely researched and reported, the novel type iridium complex included by the present invention has the advantages of high lighting efficiency, stable chemical substances and easy sublimation and purification and the like. In addition, due to introduction of a heavy electron donor carbine ligand structure, lighting color of the complex can be effectively regulated. By modifying the molecular structures of the first primary ligand and the second primary ligand, lighting positons of the complex can be adjusted within wavelength ranges of all visible lights, which provides convenience for design of organic electroluminescence displayers and lighting sources. Meanwhile, the introduced synthesis method of a series of novel iridium complexes is simple and high in yield and is flexible in chemical modification of the first and second primary ligands.
