Kajiki, Takahito; Komba, Shiro; Iwaura, Rika published the artcile< Supramolecular Organogelation Directed by Weak Noncovalent Interactions in Palmitoylated 1,5-Anhydro-D-Glucitol Derivatives>, COA of Formula: C6H12O6, the main research area is palmitoylated anhydro glucitol supramol organogelation noncovalent interaction; carbohydrates; gelators; hydrogen bonding; nanofibers; self-assembly.
We synthesized a series of novel alicyclic compounds by modifying 1,5-anhydro-D-glucitol with two to four palmitoyl chains, and we explored their self-assembly and gelation behaviors in paraffin. The obtained organogels were studied by field emission SEM, at. force microscopy, variable-temperature Fourier transform IR spectroscopy, X-ray diffraction anal., polarized optical microscopy, and transmission spectroscopy. While all the palmitoylated derivatives spontaneously formed fibrous networks and gelated the paraffin, an acetylated derivative of 1,5-anhydro-D-glucitol did not gelatinize the solvent, thus indicating the importance of aliphatic chains for gelation. Interestingly, α- and β- D-glucopyranose with five palmitoyl chains neither gelatinized the solvent nor formed fibrous networks, thus suggesting that the absence of C-1 substitution in 1,5-anhydro-D-glucitol is important for gelation. Fourier transform IR spectroscopy suggested that the formation of weak hydrogen bonds between the carbonyl groups and the C-H groups was the driving force for formation of the supramol. fibers and for gelation of the solvent.
