Title:
ORGANIC COMPOUND AND APPLICATION THEREOF IN PHOTOELECTRIC FIELD
Document Type and Number:
WIPO Patent Application WO/2022/078434
Kind Code:
A1
Abstract:
Disclosed is a compound comprising at least one structural unit of chemical formula (1) or (2). The compound comprises an alcohol-soluble or water-soluble group. The photoluminescence spectrum of the compound has a narrower half-peak width, and a color conversion layer made from the compound can absorb incident light of a wider half-peak width and then emits exit light of a narrower half-peak width. The alcohol-soluble or water-soluble group makes the compound easy to dissolve in an environmentally-friendly solvent to form a printing ink, and the peak position of the photoluminescence spectrum of the compound can be adjusted by modifying a molecular structure of the compound. Compounds of different chemical structures can be prepared into different types of color conversion layers, and can emit spectra of different colors, respectively. These light-emitting devices of different colors and narrow half-peak width can prepare display devices having high color gamut.
