A novel type of small organic gelators : Bis(amino acid) oxalyl amides

Bis(S)-leucine (1) and bis-(R)-α-phenylglycine (2) oxalyl amides are discovered to be efficient small organic gelling agents capable of gelating water while their stereoisomers meso-1 and meso-2 as well as their racemates are found to be non- gelling and poorly gelling, respectively ; IR, fluorescence emission spectroscopy and TEM are used to study assemblies of (S, S)-1 and (R, R)-2 in gels.
