AI Technical Summary
When existing Steinhaus-like compounds are used as photochromic molecules, they are in an amorphous state and lack mechanical strength, which limits their development in certain application areas. Furthermore, ultraviolet light-driven photochromic molecules may cause irreversible damage. Therefore, it is necessary to develop polymerizable photochromic isomers driven by visible light.
By preparing donor-acceptor Steinhaus adducts containing acrylate double bonds and combining them with conjugated triene moieties, visible light-driven photoisomerization is achieved, and the adducts are covalently linked to a polymer network to form polymerizable photoisomerizable donor-acceptor Steinhaus adducts.
Reversible photoisomerization under visible light was achieved, exhibiting excellent negative photochromic properties and good stability, making it suitable for the field of smart materials and expanding the application range of Steinhaus-like compounds.
