Structural control of alkylammonium-Au(dmit)(2) LB films

The structure of conductive LB films based on dioctadecyldimethylammonium-A u(dmit)(2) (2C(18)-Au(dmit)(2)) is studied by introducing into a parameter, "waiting time", which is defined as the time between the application of sp reading solvent and the onset of compression. The pi-A isotherms and the Br ewster angle microscopy suggest that 2C(18)-Au(dmit)(2) complex forms multi -layered films on the water surface, whereas, the in-plane conductivity of the LB films after anodic oxidation increases with increasing the "waiting time".
