Abstract
A class of bistable stator-rotor molecules is described. The stationary part connects the two electrodes and facilitates electron transport between them. The rotary part, which has a large dipole moment, is attached to an atom of the stator via a single sigma bond. Hydrogen-like bonds formed between the rotor’s oxygen and stator’s hydrogen atoms make the symmetric orientation of the dipole unstable. The rotor has two potential minima with equal energy for rotation about the sigma bond. The dipole can be flipped between the two states by an external electric field. The two rotor-orientation states have different current-voltage characteristics, so they are distinguishable electrically. Theoretical results on conformation, energy barriers, retention times, switching voltages, and current-voltage characteristics are presented for a particular family of stator-rotor molecules.
