Study on The Orientation of AIDF in LB Films

:In this paper the multiplayer LB films of AIDF are prepared. Polarized FT-IR spectrum and polar-ized UV-Vis spectrum are respectively used to calculate the orientation of alkyl chains component and the ori-entation of rings of AIDF in LB films. The results show: the angle between the alkyl chain axis and the vertical line of the film surface is 50? the angle between the ring axis and the vertical line of the film surface is a-bout66? Therefore we assum the structural model of molecules which arrang in LB films.
