Résumé
The main objective of this study concerns the contribution of supramolecular chemistry at differentlevel of membrane science. During the first part of our work, we have studied the dynamic selforganizingcapacities of bolaform molecules. Different characterization techniques allowed us todefine different structures, including ion or water channels for some of them. Transport capacities ofthose self-assembling molecules through lipid bilayers have been determined by several tests. Anotherstudy is about the use of a hydrophobic environment, by supramolecular interactions such as Van derWaals forces, to confine new functionalization inside mesoporous materials. Different materials,which use is determined by the confined molecules, have been obtained and characterized by severalanalysis methods. Furthermore, we have studied and optimized the use of electrodeposited silicematerials on electrodes surface, then functionalized by alkyl groups, to form electrochemical captorsby studying specifically the fullerene case.
