✦ Synopsis

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.

## Abstract The phase behavior of so called “hairy rod”‐like polymers with mesogenic elements in the side chains was investigated by means of differential scanning calorimetry and X‐ray diffraction and correlated with the properties of their monolayers at the air/water interface. The side chains of
