The spreading behavior of new type of chiral and achiral rigid cyclic oligomer on the water surface was investigated by measuring the surface pressure(π) area( A ) isotherms, with the aim of comparison of new type LB films of chiral and achiral rigid cyclic oligomers. Molecular resolution atomic force microscope images of the Langmuir Blodgett(LB) film was observed and the structure of their two dimensional crystals on the basal plane of mica was studied.
