Recent progress in metallic Langmuir-Blodgett films based on TTF derivatives
Recent progress in metallic Langmuir-Blodgett (LB) films is reported. First, we review several highly-conducting LB films focusing on the choice of donor molecules, DC conductivity and infrared absorption. From the above, difficulties in the fabrication of metallic LB films based on tetrathiafulvalene (TTF) derivatives are summarized. Among them, it is discussed comparatively that the mixing of an oxygen substituted TTF-type donor bis-ethylenedioxy-tetrathiafulvalene (BEDO-TTF) and behenic acid provides metallic LB films, which clearly exhibit a metallic temperature dependence of DC resistivity without any remarkable trace of percolation at low temperatures.
