Intermolecular central to axial chirality transfer in the self-assembled biphenyl containing amino acid–oxalamide gelators

Abstract

Chiral amino acid and biphenyl incorporating oxalamide gelators 4–7 with large, 9 bond distance between chiral centres and biphenyl units have been studied. CD investigation of 4-octanol gel and the crystal structure of rac-4 reveal that efficient central to axial chirality transfer occurs by intermolecular interactions in gel and solid state assemblies.
