Physicochemical insights in supramolecular interaction of fullerenes C60 and C70 with a monoporphyrin in presence of silver nanoparticles

► The present article introduces a newly designed monoporphyrin molecule, 1. ► For the first time, fullerene-porphyrin interaction is studied in presence of AgNp. ► Binding of fullerenes with 1 is clearly demonstrated by fluorescence studies. ► 1 serves as an effective molecular tweezers for C70 in presence of AgNp.
