Strong acceptor‐weak acceptor system FN‐TPy has been designed and synthesized, which undergoes solvent dependent self‐assembly in mixed aqueous media to generate through space intermolecular charge transfer assemblies. The as‐prepared entropically favoured assemblies of FN‐TPy exhibit excellent photostability and photosensitizing properties in the assembled state to activate aerial oxygen for efficient generation of reactive oxygen species through Type‐I and Type‐II pathways. The FN‐TPy exhibits excellent potential for regulated oxidation of alcohols and aldehydes under mild reaction conditions (visible light irradiation, aqueous media, room temperature) using aerial oxygen as the ‘oxidant’. The present study demonstrates the potential of FN‐TPy assemblies to catalyse controlled oxidation of benzyl alcohol to benzoic acid.
