    Abstract:

    In order to study the solvent effect of organogels, aromatic alcohol derivatives containing single chain alkoxy, S-C12/ S-C14/ S-C16, and three chain alkoxy T-C14 were synthesized. The gelation properties of compounds were tested and the impact of the number of side chains was analyzed by comparison. Gelation test showed that the aromatic alcohol derivatives can readily form stable gels in a variety of organic solvents. Anion test showed that the series of gels can respond to anionic stimulation. The microstructure of gels was observed and analyzed by SEM, the driving force of the gel formation was investigated by 1HNMR and IR. Through the method of Teas parameter, the characteristics of interaction between the series of gelators and the solvents were analyzed and summarized, in addition the prediction region of S-C14 where could form gels in unknown solvents was obtained and the validity of it was verified. To further investigate the solvent effect of intermolecular hydrogen bonding gelators, the hydrogen bond donor ability, the hydrogen bond acceptor ability and the polarisability of solvents which effect the gel performance were analyzed by Kamlet-Taft parameter. In addition, the validity of the conclusions was verified by other gelators.
