Self-Assembly Directed by NH-O Hydrogen Bonding
Read full article onlineFull Article
Following comments on the nature of hydrogen bonding as well as on self-assembly as it applies to supramolecular systems, the role of N − H…O hydrogen bonding in the formation and properties of a variety of supramolecular structures obtained by self-assembly from their molecular components is reviewed. The structures, which range from simple host–guest systems to complex entities such as nanotubes and hydrogen-bonded polymers, serve to exemplify the manner by which hydrogen bonds of the above type may be utilized in achieving particular molecular architectures.
Emphasis in the treatment is given to structure–function relationships underlying the various architectures described.
