Abstract:
We previously reported supramolecular polymers formed by π-π stacking between disc-shaped hexamers (rosettes) of barbituric acid-functionalized π-conjugated molecules. Herein, we investigated the impact of amide-mediated hydrogen bonding along two types of polymer backbones formed by distinct stacking of rosettes. The stabilization of the hydrogen bonds strongly depends on the intrinsic stacking arrangement of rosettes, which competes with the amide hydrogen-bonding.

Noncovalent Attractions in Biomolecules
Four types of noncovalent interactions are hydrogen bonds, van der Waals forces, ionic bonds, and hydrophobic interactions.
Hydrogen bonding results from the electrostatic attraction of a hydrogen atom covalently bonded to a strong-electronegative atom like oxygen,...
Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
