Premelting behavior of a Langmuir-Bodgett (LB) film of dioctadecyldimethylammonium-Au(dmit)2 salt was investigated using infrared transmission spectroscopy. It was observed that there were four ordered stages in the LB film below the order-disorder transition between 105-110 °C. It was also observed that the orientation and conformation of hydrocarbon chain did not change significantly in the temperature range of 30-50 °C. The results show that 2C18-Au(dmit)2 LB film exhibits high inplane conductivity of 2 Scm-1 after electrochemical oxidation.
