Bolaamphiphiles sugar-based

Borate esters of furanoid ds-l,2-diols were shown by combined B NMR, NMR and X-ray studies to form bis(diolato)borate anions, such as 27. B NMR experiments have also been employed to investigate complexes between sugar-based bolaamphiphiles, such as the glucuronamide derivative 28, and the aromatic boronate 29. ...

Bolaform sugar amphiphiles 68 exhibit columnar mesophases [154]. The aggregated structures of 68 in aqueous media depend on the stereochemical factors of the spacers. Layered structures are formed in crystalline states by self-assembly of glucopyranose-based bolaamphiphiles due to the cooperation of the hydrogen-bonding interactions of hydroxyl groups and amide linkages [155].
