Reversible conductance transitions are demonstrated on the molecular scale in a complex of 3-nitrobenzal malononitrile and 1,4-phenylenediamine, by application of local electric field pulses. Both macroscopic and local current-voltage (IV) measurements show similar electrical bistability behavior.The mechanism of the electrical bistability is discussed.
