The supramolecular organogelation of alcohols was observed in relatively hydrophobic amphiphiles with a short oligo(ethylene glycol) unit and three long alkyl chains at room temperature, while the hydrogelation occurred in more hydrophilic gelators with a longer poly(ethylene glycol) unit and two long alkyl chains at various temperatures. When a hot aqueous solution of some of the synthetic hydrogelators
在室温下,在具有较短的寡(乙二醇)单元和三个长烷基链的相对疏水性两亲物中观察到醇的超分子有机凝胶化,而在具有较长的聚(乙二醇)单元和两个长烷基的较亲水性胶凝剂中发生了水凝胶化。不同温度下的链条。当一些合成水凝胶器的热水溶液冷却后,在室温下形成超分子水凝胶。在室温下,在水中与分子间相互作用较少的其他两亲物中,通过升高其水性系统的温度(尤其是低于生理温度37°C),观察到了溶胶向凝胶的反相转变。
