The Mg|(LB monolayer)|Ptstructures of Z-β-(1-hexadecyl-4-quinolinium)-α-cyano-4-styryldicyanomethanide (C16H33–Q3CNQ) show asymmetric current–voltage characteristics; the behaviour is attributed to the organic monolayer although whether it is due to the presence of the permanent dipole moment or molecular rectification is unclear.

The efficient synthesis of a range of highly polar novel zwitterionic D-π-A adducts of tetracyanoquinodimethane (TCNQ) has been established and derivatives with an alkyl chain as short as eight carbon atoms have been fabricated as Langmuir–Blodgett (LB) films.

Macroscopic and nanoscopic current-voltage measurements reveal asymmetries in the DC electrical conductivity through Langmuir-Blodgett multilayers and even monolayers of gamma-(n-hexadecyl)quinolinum tricyano-quinodimethanide, C(16)H(33)Q-3CNQ (5) These asymmetries are due to a transition of the ground-state zwitterion to an excited-state conformer which is probably neutral. Unimolecular electrical rectification by monolayers of 5 is unequivocally confirmed.
