parallel, forming double anti-parallel chains of intermolecular hydrogenbonds using two pairs of >NH and >CO groups. In case of C6 and C7, gelator molecules were stacked through a single chain of intermolecular hydrogenbonds using a pair of >NH and >CO groups. The remaining pair of >NH and >CO groups formed an intramolecular hydrogen bond.

pharmacological activity of drugs and can even lead to new functions such as spin filters. Although there have been significant advances in understanding and controlling the helical organization of enantiopure synthetic molecular systems, rationally dictating the assembly of mixtures of enantiomer (including racemates) is nontrivial. Here we demonstrate that a subtle change in molecular structure coupled with
