Suitably modified bilayer lipid membranes (BLMs) offer exceptionally good opportunities for probing the electric field effects on charge transfer and redox reactions in biosensor and molecular electronics research and development. This work presents an attempt to form an ultrathin electron-conducting matrix for a biosensing redox device on the basis of a BLM modified with tetracyano-p-quinodimethane (TCNQ), a well-known compound forming charge transfer complexes of ‘organic metal’ behavior. The rationale behind the choice of membrane modifier was the reports of its unusual rectifying current–voltage characteristics when incorporated into BLMs alone or as part of an σ-bridged donor–acceptor molecule of C16H33–Q3CNQ (Z-β-(1-hexadecyl-4-quinolinium)-α-cyano-4-styryldicyano methanide) deposited in the form of a Langmuir–Blodgett film.
