Two-dimensional supramolecular self-assembly: nanoporous networks on surfaces.

This tutorial review addresses the formation and properties of surface-confined molecular networks as revealed with scanning probe microscopy tools, especially scanning tunneling microscopy. It could be of interest to all interested in surface nano-engineering, and supramolecular chemistry on surfaces. More specifically, this review highlights recent developments in the design of regular nanoporous networks, with a pore diameter ranging from 1 nm to more than 10 nm. The principles leading to their formation are treated in detail and the various functionalities of these porous networks are demonstrated.
