Abstract

The present application discloses a kind of compound comprising at least one chemical formula (1)-(4) structural unit, such compound comprises an alcohol-soluble or water-soluble group. Such compound has a large molar extinction coefficient, and the color conversion layer made of it can effectively absorb incident light, facilitating the preparation of a thinner color conversion layer. The alcohol-soluble or water-soluble group allows the compound to be easily dissolved in environmentally friendly solvents, forming a printing ink. Moreover, the peak position of the absorption spectrum of the compound can be adjusted by modifying its molecular structure. Different types of color conversion layers can be prepared using compounds with different chemical structures, capable of absorbing different colors of light. Light-emitting devices using such compounds can produce display devices with high color gamut.
