Improvements in the design of receptors for the detection and quantification of anions are desirable and ongoing in the field of anion chemistry, and remarkable progress has been made in this direction. In this regard, the development of luminescent chemosensors for sensing anions is an imperative and demanding sub-area in supramolecular chemistry. This decade, in particular, witnessed advancements in chemosensors based on ruthenium and iridium complexes for anion sensing by virtue of their modular synthesis and rich chemical and photophysical properties, such as visible excitation wavelength, high quantum efficiency, high luminescence intensity, long lifetimes of phosphorescence, and large Stokes shifts, etc. Thus, this review aims to summarize the recent advances in the development of ruthenium(II) and iridium(III)-based complexes for their application as luminescent chemosensors for anion sensing. In addition, the focus was devoted to designing aspects of polypyridyl complexes of these two transition metals with different recognition motifs, which upon interacting with different inorganic anions, produces desirable quantifiable outputs.
在阴离子化学领域，改进用于检测和定量阴离子的受体的设计是可取的并且正在进行的，在这方面已经取得了显著的进展。在这方面，发展用于阴离子传感的发光化学传感器是超分子化学中一个必要且苛刻的子领域。特别是在这十年中，基于钌和铱配合物的化学传感器在阴离子传感方面取得了进展，这要归功于它们的模块化合成以及丰富的化学和光物理性质，例如可见激发波长、高光量子效率、高发光强度、长磷光寿命和大斯托克斯位移等。因此，本综述旨在总结最近在开发基于钌(II)和铱(III)的配合物作为用于阴离子传感的发光化学传感器方面的进展。此外，重点还在于设计这两种过渡金属的具有不同识别基序的多吡啶配合物，这些配合物与不同的无机阴离子相互作用，产生所需的可量化输出。
