We use quantum mechanics to characterize the structure and current-voltage performance of the Stoddart-Heath rotaxane-based programmable electronic switch. We find that the current when the ring is on the DNP is 37?58 times the current when the ring is on the TTF, in agreement with experiment (ratio of 10?100). This establishes the basis for iterative experimental?theoretical efforts to optimize systems for molecule-based electronics which we illustrate by predicting the effect of adding a group such as CN to the rotaxane.
