Abstract |
Merocyanine-sulfonate photoacid have been reported over the past few years for controlling proton transfer in chemical, material and biological processes. Sulfonate-functionalized merocyanine photoacid (MEH) undergoes a cyclization reaction under visible light to form a protonated spiropyran (SPH), which is highly acidic. Sulfonate-functionalized merocyanine acts as a photoacid. On irradiation of visible light, it can reversibly change magnitude of proton concentration. Protonated spiropyran (SPH) releases a proton to form a spiropyran.
In this study, merocyanine-sulfonate type photoacid has been synthesized and its reversible photochromic reaction has been investigated by absorption and fluorescence spectroscopic methods. |
