综述了近五年来在刺激反应催化领域取得的进展，重点介绍了最近出现的新方向和应用。讨论了无金属催化剂和有机金属络合物，以及对各种有机转化表现出可切换催化活性的仿生体系和扩展结构。光致变色分子组成的光致变色体系能够基于与光异构化相关的几何和电子变化来调节反应速率、产率或对映体选择性，是详细讨论的重点。可供选择的刺激，包括pH和温度，既可以单独应用，也可以与光结合使用，也可以讨论。最近的进展清楚地表明，通过外部刺激微调催化剂行为的能力是一个强大的工具，可能会改变可持续化学的格局。
The advances made in the field of stimuli‐responsive catalysis during the last five years with a focus on the novel recently‐emerged directions and applications have been surveyed. Metal‐free catalysts and organometallic complexes, as well as biomimetic systems and extended structures, which display switchable catalytic activity for a variety of organic transformations, are discussed. Light‐activated systems comprised of photochromic molecules capable of modulating reaction rate, yield, or enantioselectivity based on geometric and electronic changes associated with photoisomerization are the focus of the detailed discussion. Alternative stimuli, including pH and temperature, which could be applied either alone or in combination with light, are also addressed. Recent advances clearly demonstrate that the capability to finely tune catalyst behavior via an external stimulus is a powerful tool that could alter the landscape of sustainable chemistry.
