Problems solved by technology

Usually, in order to change the color of the emitted light, electron-donating groups and electron-withdrawing groups can be added to the ligands of the luminescent material to adjust the color of the emitted light, but this scheme has a small adjustment range for the color

Abstract

The invention belongs to the technical field of organic photoelectric materials, and particularly relates to a transition metal complex used as a phosphorescent material, a preparation method of the transition metal complex and an application of the transition metal complex. By matching of Z1 and Z2, the wavelength of emitted light of the materials can be adjusted within a wide wavelength range and can be further precisely adjusted by changing heteroatoms on main ligands, so that electroluminescent materials with predictable light-emitting colors are acquired. The main ligands have the same skeleton structure, and wide-range adjustment of the wavelength of the emitted light from green light to dark red light can be realized only by changing the positions of functional groups and the positions and types of the heteroatoms on the main ligands. The prepared complex is high in light-emitting efficiency, and the preparation methods of the electroluminescent materials with different colors are basically the same and simple to operate.

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] The phenomenon of organic electroluminescence was first reported in 1963, but it was ignored due to its high voltage and low luminous efficiency. Until 1987, it was reported that OLED (Organic Light-Emitting Diode, English name Organic Light-Emitting Diode, OLED for short) device with multilayer structure appeared. Compared with traditional light-emitting diodes (LEDs) and liquid crystal displays (LCDs), OLED has the characteristics of self-illumination, clear and bright, light and thin, fast response, wide viewing angle, low power consumption, wide applicable temperature range, and simple manufacturing process. It meets the characteristics of "light, thin, small, colorful, economical, beautiful, ...
