• ]. The patterns formed by the polygons, especially the bigons, triangles, squares, and hexagons as well as molecular spoked wheels, are alike if the dithiophene corner pieces are exchanged by other corners, or if the side length is altered [19]. However, in all these cases the alkyl/alkoxy side chains at

In addition, the images provide insight into the multilayer growth of the molecular spoked wheels (MSWs), where the first adlayer acts as a template for the commensurate adsorption of molecules in

Keywords: molecular spoked wheels; scanning tunneling microscopy; self-assembled monolayers; solid/liquid interface; template; Introduction Molecular spoked wheels (MSWs) have gained increasing interest as two-dimensional (2D) carbon-based objects of adjustable sizes [1][2][3][4][5
