The conductivity as a function of pressure of bis(ethylenedioxy)tetrathiafulvalene 2-decyl-7,7,8,8-tetracyanoquinodinethane mono/multilayer film is reported. First conductivity is measured on the water in the Langmuir-Blodgett trough starting from separate molecules. Secondly monolayers were collected on a solid substrate and separate conductivity measurements under hydrostatic pressure (0 - 14.5 kbar) were made. The ambient pressure conductivity of the 20 monolayer films increased more than one order of magnitude from that of the monolayer conductivity at the air/water interface: ≈0.6 S/cm. The conductivity was further increased by the hydrostatic pressure (−2 at 10 kbar). At the same time the temperature of the maximum conductivity begun to shift to higher temperatures after 6 – 8 kbar. Thermal fluctuation induced tunnelling model describes well the conductivity behaviour under hydrostatic pressure at low temperatures.
