摘要
Gemini表面活性剂是由两个单头单链表面活性剂在头基处或靠近头基处由连接基团通过化学键连接而成的一类表面活性剂,它具备许多优于传统单链表面活性剂的特征和性质。它的高效性可大大降低表面活性剂的用量。由于Gemini表面活性剂自身具有很强的自组装能力,当与聚合物,生物分子以及有机小分子等复配以后,会产生更强的聚集能力和更为丰富的聚集行为。我们课题组一直从事新型Gemini表面活性剂的自组装以及Gemini表面活性剂与聚合物或生物大分子相互作用方面的研究,已发表综述总结了我们所取得的研究成果[1]。近年来,我们进一步开展了基于Gemini表面活性剂复配体系的自组装研究,发现Gemini表面活性剂在与双亲水嵌段共聚物[2],淀粉样多肽Aβ[3],以及四臂羧酸盐有机小分子[4]的复配体系中均显示出明显优于传统单链表面活性剂的性质和功能,这取决于它具有两个带电头基和两条疏水链,可以与聚合物,生物分子以及有机小分子产生更强的静电作用和疏水作用,因此具备更强的调控和组装能力。Gemini表面活性剂自身具有很强的自组装能力,因此很少量的Gemini表面活性剂就能够达到需要较多量单链表面活性剂才能达到的效果,这个高效性的特点将使Gemini表面活性剂在许多实际应用领域具有应用前景。
Gemini surfactants are constructed by two hydrophobic chains and two polar/ionic head groups covalently connected by a spacer group at the level of the head groups.Their strong self-aggregation ability can be applied to effectively influence the aggregation behavior of the complex systems based on gemini surfactants with polymer,biomolecules and small organic molecules.The unusual efficiency and versatility of gemini surfactants offer the possibility of developing the more efficient and functional gemini surfactant complex system with the less surfactant consumption and pollution.It is therefore important to systematically characterize the interactions between gemini surfactants and other complex molecules,which can offer effective guidance to design the gemini surfactant complex systems with desired properties and functionality using such highly efficient surfactants.
