Positionally isomeric gelators: Members of a series of positionally isomeric gelators based on long alkyl chains, a hydrogen-bonding phenylglycine unit, and a terminal carboxylic acid or sodium carboxylate moiety (see figure) have been found to display significantly different gelation properties. Dramatic differences in gelator effectiveness (Geff) values of up to 70 times could be observed between racemate/enantiomer gelator pairs, an effect that was observable even in the gelation of very similar solvents such as isomeric xylenes.
