Abstract

The process of molecular organization during the film compression of dithiolium-anion salts has been studied by determining the surface pressure-area and surface potential-area isotherms together with ellipsometric measurements. These experiments have been carried out as a function of different parameters such as the presence of salts in the subphase, temperature, and pH. We have demonstrated that the ellipsometric angle is sensitive to the involved polar heads. In particular, the dithiolium-TCNQ salt exhibits both a peculiar monolayer organization and a multilayer formation associated with a Z-type transfer which is due to a special anion-cation molecular arrangement.
