Nona Lett. 2004, 4, 133-136 have been used as the bottom electrode for molecular electronic devices incorporating bistable [2]catenanes and [2]rotaxanes. Recently, it has been established that devices incorporating metals as the bottom electrode do not switch as a result of a molecular-based process. Rather, the observed bistability is probably a result of reversible filament growth between the two electrodes. This result does not pertain, however, to devices operating at low bias voltages (±2 V) and incorporating semiconductors (polysilicon, for example) as the bottom electrode. To date, all of the available experimental evidence suggests that these devices switch as a consequence of a molecularly based electromechanical mechanism.
