超分子凝胶的研究已经发展成为材料科学中一个公认的领域，属于软物质的一般领域。通过超分子相互作用（如氢键、π-π相互作用、配位键和货车德瓦尔斯相互作用）聚集的小分子的使用为材料科学家提供了用于开发实用凝胶的聚合物化合物的替代方案。已经进一步尝试通过组分分子之间相互作用的可逆性来官能化、活化或控制这种凝胶的物理性质。这些特性的调节是通过使用机械、热、电化学、电磁和化学刺激来实现的。使用阴离子作为化学刺激物是最近的发展，也是本透视图的主题。
The study of supramolecular gels has developed into a well-recognised field of materials science, pertaining to the general area of soft matter. The use of small molecules that aggregate through supramolecular interactions (such as hydrogen bonds, pi-pi interactions, coordination bonds and van der Waals interactions) has given materials scientists an alternative to polymeric compounds for the development of practical gels. There have been further attempts to functionalize, activate or control the physical properties of such gels by means of the reversibility of the interactions between the component molecules. Tuning of these characteristics has been accomplished by using mechanical, thermal, electrochemical, electromagnetic and chemical stimuli. The use of anions as a chemical stimulus has been a recent development and is the subject of this Perspective.
