Aromatic oligoamide macrocycles exhibit strong preference for highly directional association. Aggregation happens in both nonpolar and polar solvents but is weakened as solvent polarity increases. The strong, directional assembly is rationalized by the co

The self-assembly of two novel intramolecular hydrogen bonding-driven foldamers is described. Two linear symmetric aromatic amide oligomers, 1 and 2, which are incorporated with benzene subunits, have been prepared by continuous amide-coupling reactions. The existence of three-centred hydrogen bonds in the oligomers and consequently the folding conformation of the oligomers in solution have been characterized by 1H NMR experiments and by comparing them with the reported solid state structure of the identical structural skeleton. Molecular modeling reveals a rigid crescent conformation for 1 with a cavity of ca. 0.9 nm in diameter and a helical conformation for 2 with a cavity of ca. 0.8 nm in diameter. Due to the existence of intramolecular hydrogen bonding, all the C=O groups in both oligomers are located inwardly. The binding of 1 and 2 towards a trihydroxyl guest and four saccharide derivatives have been investigated with 1H NMR, fluorescence, and circular dichroism spectroscopy. The association constants of the corresponding 1:1 complexes have been determined by fluorescence titration experiments.

Highly efficient, one-step macrocyclizations leading to the formation of macrocyclic hexa(aramides) in high yields (69-82%) are described. The one-step macrocyclizations were facilitated by the preorganization or folding of the backbones of uncyclized pre

A hydrogen bonding approach has been developed to facilitate the self-assembly of a new series of rigid and planar metallocyclophanes. Two new anthranilamide derivatives 1 and 2, which are incorporated with two acetylene units, respectively, have been synthesized and characterized. X-ray analysis (for 1), 1D and 2D 1H NMR and IR experiments reveal that, due to the formation of intramolecular three-centered hydrogen bonding, both compounds adopt rigid and planar conformations with the two acetylene units located at the same side of the anthranilamide skeleton. Two new metallocyclophanes 17 and 18 have been constructed in moderate yields from the reaction of 1 and 2 with trans-Pt(PEt3)2Cl2, respectively, in dichloromethane in the presence of diethylamine and cupric chloride. Fluorescent and 1H NMR investigations reveal that both 17 and 18 can efficiently complex mono- and disaccharide derivatives in chloroform, with a binding selectivity for disaccharides, which is driven by intermolecular hydrogen bonding.
