Molecular gels are formed by the self-assembly of low-molecular weight compounds by weak non-covalent interactions and thus, they may be easily disassembled in response to external stimuli. Chemically sensitive gels can be prepared by introducing in the molecular design functional groups that may interact either by covalent or non-covalent forces with other molecules present in the medium. Functional molecular gels have been reported that are sensitive to acids, bases, ions, redox-active compounds, neutral species, reactive compounds and enzymes. Here we present a broad revision of the different chemical inputs that can be used to tune gel properties through some appealing application-based selected examples.
分子凝胶是由低分子量化合物通过弱非共价相互作用自组装形成的，因此它们可以很容易地响应外部刺激而分解。通过在分子设计中引入可以通过共价或非共价相互作用与介质中存在的其他分子相互作用的官能团，可以制备对化学物质敏感的凝胶。已经报道了对酸、碱、离子、氧化还原活性化合物、中性物质、反应性化合物和酶敏感的功能性分子凝胶。在这里，我们广泛回顾了可以通过一些有吸引力的基于应用的选择示例来调整凝胶性质的不同化学输入。
