Abstract

The invention belongs to the technical field of an organic optoelectronic material, and particularly relates to a transition metal complex used as a phosphor material, and a preparation method and application thereof. Through the matching of Z1, Z2 and Z3, the emission light wavelength of the material can be regulated in a large wavelength range; meanwhile, main ligands further and finely regulatethe wavelength of the emitting light through heteroatoms, thus realizing the important value on luminous materials with various wavelengths. The prepared complex has high luminous efficacy; the wavelength of the emission light is adjustable in a large range. The main ligands of the complex have the same framework structure. By changing the functional group positions, positions of the hetero atomson the main ligands and the types of the hetero atoms, the large-range regulation of the emitting light wavelength from the emitting light wavelength to dark red light can be realized. In addition, the preparation methods of luminous materials of different colors are basically identical; the operation is simple.

Description

technical field [0001] 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. Background technique [0002] Organic electroluminescent device (OLED), as a new generation of display technology, overcomes the shortcomings of the first generation of CRT displays, such as bulky, bulky, and high power consumption, and also overcomes the shortcomings of LCD displays such as small viewing angle, slow response speed, unusable at low temperature, and The lack of self-luminescence, its biggest breakthrough lies in the mechanical toughness of the material, low-temperature process and sandwich device structure, not only can obtain better visual effects than conductive structure LCD, but also can be applied on any thin and light substrate, with very Attractive application prospects, great development potential.
