Conducting Langmuir-Blodgett (LB) films based on a new asymmetrical tetrathiafulvalene (TTF) and its charge transfer complex with TCNQ were prepared by admixing with arachidic acid. The LB films were characterized by surface pressure-area isotherms, UV spectra, and X-ray diffeaction. Conductivity of the LB films relating to the number of layers was studied. After doped with iodine the highest conductivity for the asymmetrical TTF and its TCNQ complex LB film reached 0.23 and 4.7×10-5 S·cm- 1 ，respectively.
