What is a Molecular Device

One of the ultimate goals of those developing new devices is the preparation of molecular devices, where molecules or molecular systems replace functional units. Molecular devices are expected to provide the key to the development of nanotechnology. 

This example is based on a covalently linked, complicated molecule which is difficult to synthesize. We can overcome this difficulty by using supramolecular concepts. Complicated functional systems can be constructed through the supramolecular assembly of relatively simple components. The supramolecular approach has the additional advantage of permitting us great freedom in terms of combining functional parts.
