I will describe formation, structure and reactivity of thin films of amphiphilic molecules deposited onto a metal surface at the metal-solution interface. Specifically, I will discuss how these molecules aggregate to form monolayer or bilayer films and what is their stability in the presence of electric fields that are on the order of 107 V/m. I will show how these fields affect ordering of molecules within the film and how they cause a phase transitions in the film. I will then discuss various applications of molecular films in corrosion protection, metal electrodeposition, biosensors and molecular electronics.
