摘要

手性表面活性剂是一类两亲化合物,其特点是亲水头基和疏水尾基,分子结构中含有一个或多个手性中心。除了具有典型的表面活性剂特性外,它们还表现出固有的不对称性。通过取代手性基团或在手性中心引入官能团,可以有效调节它们的聚集行为和自组装结构。人们已经做出了许多努力,来制作具有复杂理化特性和新兴应用的手性表面活性剂。本综述将深入探讨来源不同、分子结构各异的手性表面活性剂的聚集行为,重点关注头基、间隔基和反离子等关键参数。此外,还总结了这些多功能手性表面活性剂在多个活性领域的应用,包括手性识别、对映体分离、不对称催化和手性纳米材料的合成。最后,报告概述了与手性表面活性剂相关的前景和未来挑战,强调了在这一领域进一步探索和进步的途径。

Chiral surfactants: Design, aggregation behaviors and applications

Chiral surfactants represent a class of amphiphilic compounds characterized by hydrophilic headgroups and hydrophobic tails, coupled with one or several chiral centers within their molecular structures. Beyond possessing typical surfactant properties, they exhibit inherent asymmetry. Their aggregation behaviors and self-assembled structures can be effectively modulated by substituting chiral groups or introducing functional groups at the chiral center. Numerous endeavors have been undertaken to craft chiral surfactants with sophisticated physicochemical properties and burgeoning applications. This review delves into the aggregation behaviors of chiral surfactants sourced from various origins and possessing different molecular structures, with a focus on key parameters including headgroup, spacer and counterion. Moreover, applications of these multifunctional chiral surfactants are summarized across several active domains, including chiral recognition, enantiomer separation, asymmetric catalysis and the synthesis of chiral nanomaterials. Finally, it outlines perspectives and future challenges associated with chiral surfactants, highlighting avenues for further exploration and advancement in this field.

期刊介绍: Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
