Synthesis of spiropyrans exhibiting ring-opening/closing isomerization driven by external stimuli is a challenging subject for the development of molecular sensors. A napthalimide-containing spiropyran ( ) promotes rapid isomerization between the spirocyclic (SP) form and ring-opened merocyanine (MC...
