Patterns consisting of 10 nm stripes of Au55(PPh3)12Cl6 clusters have been generated by degradation of two-dimensional, ordered cluster monolayers on a water surface. Applying a modified Langmuir–Blodgett technique stripe formation is induced by fast withdrawing (10 cm min−1) of a substrate, deposited underneath the monolayer, under an angle of 20°. The stripes, each consisting of 3–4 cluster rows, show a separation 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.
