尽管人们对有机胶凝剂和水胶凝剂进行了大量的研究，但关于能够同时胶凝有机溶剂，特别是非极性溶剂和水的双极性胶凝剂的报道非常有限。为了创造有效的ambiaculus胶凝剂，应该采取自下而上的方法。因此，根据分子设计，已经制备了由具有两个长烷基链和乙醇胺部分的基于谷氨酸盐的结构组成的两亲性化合物。已经发现具有C6和C7烷基链的化合物作为优异的双极性能力起作用，因为它们只能胶凝水和非极性溶剂。虽然具有C9和C10烷基链的化合物在水中没有显示出凝胶化，但是通过将铵阳离子引入这些化合物中获得了两亲性。通过与少量的真正的Ambiphilus胶凝剂混合，可以将Ambiphilus能力赋予不具有Ambiphilus性质的化合物。
Although tremendous research investigations on organogelators and hydrogelators have been conducted, the reports about the ambidextrous gelators capable of gelating both organic solvents, especially, apolar solvents and water are very limited. In order to create efficient ambidextrous gelators it should be necessary to take a bottom‐up approach. Thus, according to molecular design the amphiphilic compounds consisting of glutamate‐based structure having two long alkyl chains and the ethanolamine moiety have been prepared. The compounds having C6 and C7 alkyl chains have been found out to work as an excellent ambidextrous capability because they can only gelate water and apolar solvents. Although the compounds having C9 and C10 alkyl chain showed no gelation in water, by introduction of an ammonium cation into these compounds ambidextrous properties were gained. Ambidextrous ability can be imparted to the compound having no ambidextrous properties by mixing with a small amount of an authentic ambidextrous gelator.
