Problems solved by technology

[0003] Compared with the wide application of traditional organic dye molecules in the research fields of organic functional materials and devices, the application of chiral dye molecules in optoelectronic devices is very limited, mainly due to the lack of types of chiral organic dye molecules that limit chirality. The development of optoelectronic devices
At present, the main strategy to obtain chiral organic dye molecules is to introduce chiral groups into simple organic dye molecules, but it is often limited by the difficulty of preparation and the availability of species.
