Abstract
Conducting Langmuir-Blodgett films are one of the candidates for molecular electronics. We investigated the structural and electrical properties of Langmuir-Blodgett films built up as a mixed molecular system of bis(ethylenedioxy)tetrathiafulvalene, in short BEDO-TTF, and fatty acid, as a function of (a) the alkyl chain length of the fatty acid and (b) the fatty acid: BEDO-TTF molar ratio in the starting solution from which the Langmuir film is prepared. The Langmuir-Blodgett films deposited from mixtures with molar ratio 1:2 showed better quality in terms of crystallinity and electrical conduction. Moreover, LB films with longer alkyl chain fatty acids were better ordered even at lower molar ratio.
