Surface Noncovalent Bonding for Rational Design of Hierarchical Molecular Self‐Assemblies

Clip chemistry: When a fully deterministic strategy that parallels polymer chemistry is used, mono-, bi-, and trifunctional clip-bearing building blocks form noncovalent surface-self-assembled dimers, polymers, and 2D networks, respectively (see scheme). These entities can then be subjected to further higher-level manipulations, as shown by controlled reorganization (cyclization) of a polymerlike chain around a molecular block.
