Fluorescent assemblies of pentacenequinone derivative 3 bearing 3-thienyl groups served as nanoreactors for the generation of Ag@Fe3O4 nanoclusters (NCs). This sensing/reduction process was accompanied by oxidation of assemblies of pentacenequinone derivative to polymeric species 4. The as prepared Ag@Fe3O4 NCs serve as recyclable photocatalyst for the construction of indazole derivatives under mild conditions (visible light irradiation, room temperature and aerial conditions). The present investigation emphasizes the role of pentacenequinone based supramolecular assemblies as nanoreactors for generation of Ag@Fe3O4 NCs and as stabilizers as well as oxidants in the C–H to C–N bond transformation.
