New C-terminal hydrazide L-Leucine derivatives as multi-solvent low molecular weight organogelators

Résumé

Three new low-molecular-weight gelators (LMWGs) based on L-Leucine derivatives bearing different chain lengths (i.e. 9, 12 or 16) were designed and synthesized. The N-terminal carries various alkyl chain lengths while the C-terminal is modified with hydrazide moiety. The prepared gelators 1-3 were fully characterized using 1 H, 13 C NMR, FTIR and mass spectroscopy. The gelation behavior has also been investigated using different organic solvents and oils with determination of critical gelation concentration (CGC). The self-assembly process was investigated by recording FTIR spectra gel states to investigate the driving forces for gelation process. The morphology of the prepared xerogels was studied using SEM.
