Hydrogen-bonding-driven preorganized zinc porphyrin receptors for efficient complexation of C60, C70, and C60 derivatives

The self-assembly of molecular tweezers whose rigid skeletons are constructed based on the intramolecular hydrogen-bonding driven aromatic amide foldamers is described. The zinc porphyrin-based, well-ordered tweezers are efficient nonring receptors for complexation of fullerene and fullerene derived molecules like C60, C70 and C60 derivatives, due to their preorganized rigid conformation.
