Patterns consisting of 10-nm stripes of Au55(PPh3)12Cl6 clusters have been generated by degrdn. of two-dimensional, ordered cluster monolayers on a water surface. By applying a modified Langmuir-Blodgett technique, stripe formation is induced by the fast withdrawing (10 cm min-1) of a substrate, deposited underneath the monolayer, under an angle of 20 Deg. The stripes, each consisting of 3-4 cluster rows, show a sepn. of 8 nm from each other. Slow transportation of the substrate (2-3 cm min-1) led to hexagonal patterns of crossing stripes. This effect is attributed to the existence of partially overlapping islands of monolayers.
