A family of low-molecular-weight organogelators based on N-alpha,N-epsilon-diacyl-L-lysine was synthesized by acylation of N-epsilon-dodecyl-L-lysine with acyl chlorides through the one-pot synthetic procedure and their organogelation properties were examined. These compounds functioned as an organogelator; especially, L-lysine derivatives possessing the branched alkyl groups are a better organogelation property. The NMR and IR studies demonstrate that the organogelation occurred through hydrogen bonding interactions between the amide groups and between the carboxy groups. (C) 2008 Elsevier Ltd.
