The invention belongs to the technical field of organic photoelectric materials, and in particular relates to a class of transition metal complexes used as phosphorescent materials, a preparation method and applications thereof. The complex prepared by the invention not only has high luminous efficiency, but also the wavelength of emitted light can be adjusted in a wide range. The main ligands of such complexes have the same skeleton structure, and by changing the positions and types of heteroatoms on the main ligands, a wide range of emission wavelengths can be adjusted from red light to near-infrared light. In addition, the preparation methods of different color luminescent materials are basically the same, and the operation is simple. |
