Synthesis and Properties of Organogels Based on Aromatic Alcohol Derivatives

摘要:

为了研究有机凝胶的溶剂效应，合成了单链烷氧基芳香醇系列化合物S-C12、S-C14、S-C16及三链化合物T-C14。测试了其凝胶性能并对比分析了侧链个数的影响，结果表明化合物在多种溶剂中具有较好的凝胶性能。阴离子测试结果表明，该系列凝胶化合物可以对阴离子刺激作出响应。运用扫描电子显微镜观察并分析了凝胶的微观结构，并通过核磁共振光谱及红外光谱研究了系列化合物的成胶驱动力。通过梯氏参数法分析并总结出该系列凝胶因子和溶剂之间相互作用的特点，获得S-C14在未知溶剂中形成凝胶的预测区域，并对该预测区域的有效性进行了验证。为了进一步研究分子间氢键型凝胶因子的溶剂效应，通过Kamlet-Taft参数法分析了溶剂得失氢键能力及极性对所合成化合物凝胶性能的影响，并利用其他系列凝胶因子对所得结论的一致性做出了验证。

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.
