Abstract Spiropyran derivatives have been extensively studied as typical photochromic molecules. The colorless non-fluorescent spiropyran form is converted into colored fluorescent merocyanine form upon ultraviolet (UV) irradiation. Spiropyrans are attractive platforms in such constructions due to their unique photochromic property and molecular recognition ability. ALthough the neutral spiropyran form cannot act as a chelating ligand for metal cations, the zwitterionic open merocyanine form has the negatively charged phenolic oxygen moiety that can act as an efficient ligand for protons and metal ions. Nitrogen ligand such as triazine could give additional chelation site. Therefore, a new spiropyran derivative containing triazine moiety was designed and synthesized. In this study, photochromic reaction of spiropyran-triazine has been investigated by ultraviolet-visible absorption and fluorescence spectroscopic measurements.
