NOR and AND logic gates based on supramolecular porphyrin-fullerene conjugates.
Supramolecular porphyrin-fullerene conjugates are employed to build NOR and AND logic gates. A crown ether appended zinc porphyrin and an imidazole or an alkyl ammonium functionalized fullerene are utilized. Quenching of zinc porphyrin fluorescence upon addition of binding-site-selective fullerene inputs forms the design basis of the NOR logic gate, while replacing the fullerene entities from the porphyrin-fullerene conjugate and restoring the original fluorescence by chemical inputs form the design basis of the AND logic gate.
