Construction of two-dimensional (2D) H-bonded supramolecular nanostructures studied by STM

In this review, a group of two-dimensional (2D) hydrogen-bonded supramolecular networks developed in our laboratory are discussed. Our attention ismainly focused on: (1) recognition of Fe3+ through twocomponent molecular networks; (2) site-selective fabrication of 2D fullerene arrays; and (3) fabrication of the nanoporous structure regulated by photoisomerization reaction process. It is envisioned that special supramolecular nanostructures, through H-bonding interactions, can be constructed or reconstructed to be further investigated toward the research of multi-component systems, molecule recognition, single molecular switches, and host-guest supramolecular chemistry.
