Résumé
We report the synthesis of a new functional molecule, a quater-tiophene based
surfactant, which can both adsorb at the water / gas interface (surface active
molecule) and aggregates through pi-pi stacking interactions. We assess then
the ability of this molecule to create these functionalities at interfaces.
This interfacial functional aggregation, characterized here in situ for the
first time, is probed thanks to Langmuir trough experiments and spectrometric
ellipsometry. These results open some new routes for the design of new water
based opto-electronic devices.
