| titleOfInvention | Compound capable of emitting white light and preparation method thereof |
| abstract | A compound capable of emitting white light and a preparation method thereof belong to the technical fields of rare earth complexes, organic chemistry and material chemistry. In the present invention, the ethanolic solution of coumarin ester and hydrazine hydrate are reacted in a reasonable proportion to obtain compound 1, compound 1 and 8-hydroxy-2-quinolinaldehyde are dissolved in ethanol and react to obtain compound CRP4, the ethanolic solution of compound CRP4 and Eu( TTA) 3 (H 2 O) 2 in ethanolic solution reaction to obtain compound CRP4-Eu. Beneficial effects: the present invention realizes single-molecule white light emission through the blue light emission of the coumarin derivative part and the red light emission of the rare earth europium complex, which lays the foundation for its application as a single-molecule white light material in the future, and this type of white light material can be used It is widely used as backlight source of liquid crystal and solid-state lighting. |
