Etude de la reconnaissance moléculaire dans les films de Langmuir formés par des cristaux liquides thermotropes et des dérivés macrocycliques amphiphiles en vue de l'élaboration de matériaux fonctionnels

Abstract : The investigation on the mechanisms of molecular recognition of small molecules and cations by amphiphilic derivatives of cyclodextrins, crown ethers and thermotropic liquid crystals was realized with the aim of elaborating supramolecular functional systems and new nanomaterials. The effects related to the molecular recognition were studied in Langmuir and Langmuir-Blodgett films. These systems allow the investigation of the intra- and intermolecular interactions involved in the recognition process via monitoring of the surface pressure, surface potential and film morphology. Various techniques, in particular Brewster angle microscopy, atomic force microscopy, fringes of equal chromatic order technique, fluorimetry, electrochemistry, differential scanning calorimetry and gas chromatography were used in order to characterize the molecular systems conceived.
