A zwitterionic molecule has been incorporated as a Langmuir-Blodgett (
LB) film between two electrodes. Current-voltage curves are presented
which exhibit rectifier-like behaviour. By placing passive organic lay
ers between the zwitterionic LB film and each electrode we show that S
chottky contact and similar interfacial effects axe not important and,
therefore, that the rectifier-like behaviour is unequivocally associa
ted with the zwitterionic molecular structure.
