Some molecules respond to light in a matter of seconds. In the case of this dithienylethene compound, UV light triggers a ring-forming reaction, turning the colorless solution deep red. Visible light reverses that reaction and color change: cen.acs.org/synthesis/ca... #chemsky🧪 #scinews #CENChemPics
