A supramolecular chemistry basis for molecular logic and computation

The ideas of supramolecular chemistry can be a useful way of advancing molecular logic and computation. Some of these cases occur at the molecular-scale while others require the intervention of bulk materials of various kinds. Even irreversible chemical reactions can provide food for thought. Logic operations from the simplest to small-scale integrated cases are now available, including those with arithmetic capability. (C) 2007 Elsevier B.V. All rights reserved.
