Abstract

The invention belongs to the technical field of organic photoelectric materials, and particularly relates to a transition metal compound used as a phosphorescent material as well as a preparation method and application thereof. The wavelength of emitted light of the material can be adjusted within a relatively large wavelength range through cooperation of Z1, Z2 and Z3; meanwhile, a main ligand further finely adjusts the wavelength of the emitted light through heteroatoms, which has an important value in obtaining luminous materials with various wavelengths. The compound prepared according tothe preparation method is high in luminous efficiency; furthermore, the wavelength of the emitted light can be adjusted within a large range. The main ligands of the compound have an identical framework structure; adjustment of the wavelength of the emitted light in a deep red light range by changing the position of a functional group, the position of a heteroatom on the main ligand and the type of the heteroatom. In addition, preparation methods of luminous materials in different colors are basically the same, and are simple to operate.

Description

technical field [0001] The invention belongs to the technical field of organic optoelectronic materials, and particularly relates to a transition metal complex used as a phosphorescent material, a preparation method and application thereof. Background technique [0002] As a new generation of display technology, organic electroluminescent device (OLED) overcomes the shortcomings of the first-generation CRT display, such as large size, bulkiness and high power consumption, and also overcomes the small viewing angle, slow response speed, unusable and unusable under low temperature of LCD display. Its biggest breakthrough lies in the mechanical toughness of the material, the low-temperature process and the sandwich device structure, which can not only obtain better visual effects than the conductive structure LCD, but also can be applied on any thin and light substrate. Attractive application prospects, huge development potential. [0003] In OLED research, the choice of organ...
