We present here the formation of giant pores in surface-confined molecular networks of a triangular-shaped dehydrobenzo-[12]annulene derivative: the diameter of the pores reaches over 7 nm and the giant pores are used as templates to accommodate a giant molecular spoked wheel, which allows us to observe rotational and adsorption-desorption dynamics of single guest molecules.rnEngineering of nanometre-scale two-dimensional (2D) molecular architectures, so-called 2D molecular networks, by surface-confined self-assembly receives considerable attention due to its relevance in nanotechnology. This approach turns out to be successful not only at the level of monolayer formation of the molecular building blocks themselves but also by 2D host-guest chemistry via binding events between the supra-molecular template layer and guest molecules. In the latter case the guest molecules could be "isolated", therefore favoring single molecule studies.
