Tetrakis(octadecylthio)Tetrathiafulvalene: Influence of Long Alkyl Chains on the Architecture and Electrochemical Properties of LB Films.
We present here a study of a tetrathiafulvalene derivative, tetrakis(octadecylthio)tetrathiafulvalene (TTFH), arranged in LB films together with a detailed characterization process by means of UV-vis, IR, SEM, and X-ray diffraction that has allowed us to propose a packing model. These films were exposed to iodine vapor and this doping process was carefully followed using UV-vis and IR spectroscopy. The redox properties of the TTFH were studied in both organic solution and LB films. The results have been interpreted in terms of the molecular structure and the LB film architecture.
