A semi-heterogeneous photocatalytic system was assembled through encapsulation of a lipophilic porphyrin in stabilized polydiacetylene micelles. The colloidal nanohybrid catalyst was valorized in the aerobic photo-oxidation of sulfides to the corresponding sulfoxides. Micelles behaved as nanoreactors by creating a favorable environment for the photo-activation of oxygen nearby thioethers and subsequent sulfoxidation. The process operates selectively under visible light and air atmosphere, with low catalytic loading and in water as the only solvent.
