A technique is described whereby a molecular circuit device functions as a flip-flop, an inverter, an OR logic gate, and as an AND logic gate. Discussed are the molecular considerations needed to construct the functional circuit configurations. (Image Omitted) Molecular conductors and semiconductors have been known for some time [1]. More recent compounds, such as polypyrrol, polyacetylene and polythiophene, have their conductivity rival that of metals, such as copper. It has been found that, invariably, the valence bands of these compounds are partially filled. Depleting the valence band is usually accomplished by charge complexation, or by oxydation. Therefore, one basic requirement for conduction in organic compounds is the presence of an unfilled electronic band.
