Description
He Li and colleagues reported light-switchable colour molecules in 2025. Spiropyran and merocyanine switch into each other. Light drives that classic colour change. New versions carry a pyridine ring here. Visible light forms a new carbon-nitrogen bond.
The switched form is a spiro product. The molecules resist repeated switching well. They also work in water. A quinoline cousin switches both ways. Two light colours drive opposite directions. Solid films showed the effect too. Step-by-step switching was demonstrated in sequence. Advanced light-based devices are the target. Colour changes were driven by visible light.
