Orientation of the liquid crystalline (LC) and command surface molecules was investigated by the surface potential and optical second-harmonic generation (SHG) measurement. LC ultra thin film was prepared on azobenzene command surface (6AZ10-PVA) LB monolayer by the evaporation. SHG measurements show that LC molecules are deposited on 6AZ10-PVA monolayer so as to compensate the hyper-polarizability...
