Abstract
A physical implementation of set-reset copper rotaxanes that is electrochemically driven was investigated. The ability of copper rotaxanes to undergo reversible geometrical reorganization between the two different metal oxidation states made them suitable for implementing memory units. A finite-state logic machine started in an initial state and processed inputs one at a time. The new state and output were determined by a transition table. A explicit finite difference numerical method was implemented to simulate the operation of the set-reset machine. The set and reset inputs were provided as an applied potential difference and the state of the machine was encoded in the two stable redox species Cu+ and Cu2+. It was observed that the state could be detected by using cathodic and anodic currents.
