Problems solved by technology

However, due to the relatively low carrier mobility in amorphous organic semiconductor materials, direct electrical pumping of organic semiconductor lasers has not yet been realized. Therefore, the effective improvement of the mobility of organic light-emitting materials will mean that organic materials and Organic semiconductor lasers will have a broader application prospect

Abstract

The invention relates to a highlight gain fluorene-benzothiadiazole copolymer luminescent material and a preparation method and belongs to the technical field of organic luminescent materials. The highlight gain fluorene-benzothiadiazole copolymer luminescent material is characterized in that fluorene and benzothiadiazole are alternatively polymerized, the modification of steric hindrance groups is carried out on the site 9 of fluorenyl, so that a dihedral angle in a molecular chain is changed, the contact probability of an energy transfer unit is increased, the electronic mobility is increased, and high luminous efficiency and good solution preparation property are maintained, and therefore, the highlight gain fluorene-benzothiadiazole copolymer luminescent material can be used as a laser material with the low threshold and high migration rate.

Description

technical field [0001] The invention relates to a fluorene-benzothiadiazole copolymer light-emitting material with high light gain and a preparation method, belonging to the technical field of organic light-emitting materials. Background technique [0002] Organic electroluminescent devices (LEDs) and optically pumped semiconductor lasers have been released, but they have not yet reached the stage of practical application, and organic electro-pumped lasers are still in the stage of experimental research and exploration. However, organic lasers, including small molecules and polymer materials as working substances, have many advantages over other inorganic lasers, so their application prospects are very broad. Organic lasers also have the advantages of simple production, low cost, and convenient integration. The emission wavelength range of organic lasers covers the entire visible light band, so it has advantages in some aspects that require collimation, coherent light or dec...
