At coverages below one monolayer pentacene was found to arrange in islands with

• an upright configuration. The molecular arrangement was resolved in high-resolution images. In these images two different types of patterns were observed, which switch repeatedly. In addition, defects were found, such as a molecular vacancy and domain boundaries. Keywords: KCl; molecular growth

• of a functionalized tip [35]. In this work, we describe the arrangement of pentacene adsorbed on the KCl(001) single-crystal surface. For submonolayer coverage the molecules form islands with upright ordering. In molecularly resolved images of these islands two different molecular patterns are
