Abstract
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 (designated as 1-3). The N-terminal is carrying the various alkyl chain lengths where the C-terminal is modified with hydrazide moiety. The prepared gelators 1-3 were fully characterized using 1H, 13C 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.
