Despite its relative simplicity, ethylene is an interesting molecule with wide-ranging impact in modern chemistry and biology. Stemming from ethylene's role as a critical plant hormone, there has been significant effort to develop selective and sensitive molecular sensors for ethylene. Late transition metal complexes have played an important role in detection strategies due to ethylene's lack of structural complexity and limited reactivity. Two main approaches to ethylene detection are identified: (1) coordination-based sensors, wherein ethylene binds reversibly to a metal center, and (2) activity-based sensors, wherein ethylene undergoes a reaction at a metal center, resulting in the formation and destruction of covalent bonds. Herein, we describe the advantages and disadvantages of various approaches, and the challenges remaining for sensor development.
尽管乙烯相对简单，但它是一个有趣的分子，在现代化学和生物学中有着广泛的影响。由于乙烯作为一种关键植物激素的作用，人们付出了巨大努力来开发用于检测乙烯的选择性和灵敏性分子传感器。由于乙烯结构复杂性不足且反应活性有限，后过渡金属配合物在检测策略中发挥了重要作用。确定了两种主要的乙烯检测方法：（1）基于配位的传感器，其中乙烯与金属中心可逆结合；（2）基于活性的传感器，其中乙烯在金属中心发生反应，导致共价键的形成和破坏。在此，我们描述了各种方法的优缺点以及传感器开发中仍然存在的挑战。
