Abstract

We have used atomic force microscopy (AFM) to study the in-plane structure in monolayer and multilayer Langmuir Blod-gett films containing disk-shaped molecules. The disks self-organize in columns parallel to the slide and aligned about the direction of deposition with a ∼ 35° distribution of orientations. Bilayer films exhibit unusual height modulations arising from the superposition of columnar features rotated with respect to one another. Preliminary results for star-shaped oligomeric species are also presented.
