A new photochromic diarylethene , 1,2‐bis(5′‐ethoxy‐2′‐(2″‐pyridyl) thiazolyl) perfluorocyclopentene ( 1 ), is synthesized. Nanoparticles are obtained by laser ablation at both 355 and 532 nm, corresponding to the absorption wavelengths of the open and the closed forms. 1 can be reversibly photoswitched in various states: organic solution, bulk crystal, nanoparticle colloidal solution, and single nanoparticle, as demonstrated by dark‐field scattering spectroscopy.
