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.
