This Minireview covers the latest developments of chemosensors based on transition-metal receptors and organic fluorophores with specific binding sites for the luminescent detection and recognition of iodide in aqueous media and real samples. In all selected examples within the last decade (made-post 2010), the iodide sensing and recognition is probed by monitoring real-time changes of the fluorescence or phosphorescence properties of the chemosensors. This review highlights effective strategies to iodide sensing from a structural approach where the iodide recognition/sensing process, through supramolecular interactions as coordination bonds, hydrogen bonds, halogen bonds and electrostatic interactions, is transduced into an optical change easily measurable. The selective iodide sensing is an active field of research with global interest due to the importance of iodide in biological, medicinal, industrial, environmental and chemical processes.
这篇综述涵盖了基于过渡金属受体和具有特定结合位点的有机荧光团的化学传感器的最新发展，用于在水相介质和实际样品中对碘化物进行荧光检测和识别。在过去十年内（2010 年后）所有选定的实例中，通过监测化学传感器荧光或磷光性质的实时变化来探测碘化物的传感和识别。本综述突出了从结构方法中碘化物传感的有效策略，其中通过超分子相互作用（如配位键、氢键、卤键和静电相互作用）将碘化物识别/传感过程转化为易于测量的光学变化。由于碘化物在生物、医学、工业、环境和化学过程中的重要性，选择性碘化物传感是一个具有全球关注的研究热点。
