  • White light emitting material, preparation method thereof, and application thereof
    Patent number: 11581489
    Abstract: A white light emitting material having a chemical structural formula represented by formula (I), a preparation method thereof and application thereof. The preparation method comprises subjecting tris(4-iodophenyl)amine and 4-methoxyphenylacetylene or tris(4-iodophenyl)amine and methyl 4-ethynylbenzoate to a coupling reaction under protection of a protective gas and catalysis of a Pd/Cu mixed catalyst, to obtain the white light emitting material. A novel temperature-sensitive light emitting material is synthesized through a one-step method. The material is applied to the field of diode luminescence based on the temperature-sensitive characteristic. White light luminescence can be finally realized only by reasonably controlling the temperature and duration time during heating a substrate. Compared with the existing art, the method greatly saves raw material costs and manufacturing process costs, and provides a novel idea and strategy for use of a white organic light emitting diode.
