Abstract

The invention relates to synthesis and characteristic determination of a novel Schiff base ligand and platinum complex, and belongs to the coordination chemistry field of inorganic chemistry, wherein the phosphorescence emission can be achieved effectively. According to the novel Schiff base ligand and platinum complex light-emitting material, the maximum ultraviolet absorption wavelength of the platinum complex is 487 nm, the maximum phosphorescence emission wavelength is 618 nm, and the decomposition temperature is 295 DEG C. The novel complex is convenient to synthesize, high in thermostability and not prone to decomposition under high temperature and can be prepared through a simple instrument.

Description

technical field [0001] The invention relates to an organic luminescent material, in particular to a yellow light luminescent material of a Schiff base platinum complex. Background technique [0002] The research on OLEDs began in the 1960s. In 1963, Professor Pope of New York University first discovered the electroluminescence phenomenon of organic material single crystal anthracene. In 1987, Tang of Kodak Company in the United States used ultra-thin film technology and a new device structure to make an organic electroluminescent device with low operating voltage and high luminous brightness, which fundamentally changed the research on organic electroluminescent materials. Subsequently, in 1990, Professor Burroughes and Professor Friend of the Cavendish Laboratory of the University of Cambridge in the United Kingdom used polystyrene (PPV) as a light-emitting material to make a polymer electroluminescent device, which opened up a polymer thin film electroluminescent device. ...
