A layer of logic: A series of Boolean operations has been demonstrated with redox-active monolayers of osmium and ruthenium complexes on glass substrates. High stability, selective reactivity, and reversible redox-chemistry, coupled with significant optical changes, make these monolayers versatile logic gates. The electron-transfer-based systems are suitable as standalone systems or as operational parts in logic circuits.
