Abstract

In conducting systems based on Langmuir - Blodgett (LB) films, tetracyanoquinodimethane(TCNQ) derivatives have been extensively studied as electron acceptor molecules. We have fabricated N-docosyl N'-methyl viologen diTCNQ (DMVT) anion radical LB film and investigated the FT-IR, ESR, and AFM images as the optical, magnetic properties and morphology of the LB film. We have measured in-plane electrical conductivity with number of layers. The in-plane conductivities are approximately $10^{-7}{\sim}10^{-6}\;S/cm$.
