The effects of oligomer length, solvent, and temperature on the self-association of stably folded short aromatic oligoamide are probed. With large flat surfaces, these aromatic oligoamides undergo stacking interaction with strength that increases nonlinearly with oligomer lengths. Opposite to typical aromatic stacking, the stacking of these molecules is enhanced in solvents of low polarity, but it is greatly weakened in polar solvents, especially those with hydrogen bond donors, and it is very sensitive to changes in temperature.

As a major class of foldamers, aromatic oligoamide foldamers have attracted intense interest. The rigidity of aromatic residues and amide linkages allows the development of foldamers with readily predictable, stable...

New aromatic oligoamide macrocycles with C3-symmetry bind bipyridinium guest G to form compact pseudo[3]rotaxes involving interesting enthalpic and entropic contributions. The observed high stabilities and strong positive binding cooperativity are...

Two aromatic oligoamides, the 8-residue H8 and 16-residue H16, that adopt stable, cavity-containing helical conformations were examined for their complexation of rodlike dicationic guest, octyl viologen (OV2+) and para-bis(trimethylammonium)benzene (TB2+)....
