“…Recently, Ramos and co-workers reported 1,5-bis(benzimidazol-2yl)-3-thiapentane-based ruthenium (II) complex 54 ( Figure 8 ) for selective detection of Cl − as a “switch on” probe even in the presence of other interfering anions such as F − , NO 3 − , Br − , HSO 4 − , I − , and H 2 PO 4 − [ 89 ]. The interaction of Cl − with the receptor complex facilitated the electron transfer from the highest occupied molecular orbital (HOMO) of the donor to low-lying HOMO of the fluorophore, i.e., acceptor as a disfavored Photo Electron Transfer (PET) process in the excited state resulted in the increasing the fluorescence intensity.…”

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.

“…The sensor had good reproducibility and reversibility. Pineda et al [79] studied the ruthenium complex of bis (benzimidazole-2-ethyl) sulfide as a fluorescence sensor for the recognition of Cl − . The sensor selectively combined with Cl − to stimulate fluorescence at 365 nm, and the detection limit of Cl − was up to 0.44 µmol/L by measuring fluorescence intensity at 453 nm.…”

The chloride ion (Cl−) is a type of anion which is commonly found in the environment and has important physiological functions and industrial uses. However, a high content of Cl− in water will do harm to the ecological environment, human health and industrial production. It is of great significance to strictly monitor the Cl− content in water. Following the recent development of society and industry, large amounts of domestic sewage and industrial sewage are discharged into the environment, which results in the water becoming seriously polluted by Cl−. The detection of Cl− has gradually become a research focus. This paper introduces the harm of Cl− pollution in the environment and summarizes various Cl− detection methods, including the volumetric method, spectrophotometry method, electrochemical method, ion chromatography, paper-based microfluidic technology, fluorescent molecular probe, and flow injection. The principle and application of each technology are described; their advantages, disadvantages, and applicability are discussed. To goal of this research is to find a more simple, rapid, environmental protection and strong anti-interference detection technology of Cl−.

The new eight‐coordinate complex of thorium(IV) was synthesized by the reaction of Th(NO3)4.4H2O with 1,10‐phenanthroline(phen) and 2‐hydroxy‐5‐sulfobenzoic acid (SSA) by coprecipitation method. An environment friendly chelating agent sulfosalicylic acid (SSA) having oxygen donor atoms, phen with delocalized π‐electron system, and N‐donor atoms were used during the preparation of complex. The complex was characterized on the basis of elemental analysis, Fourier transform infrared (FTIR) spectroscopy, UV–Vis spectroscopy, powder X‐ray diffraction (PXRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM). The complex was further assessed for structural and magnetic behavior. The results revealed that the complex has been completely formed as eight coordinated, amorphous in nature, diamagnetic, air stable, granular surface morphology, and water soluble. Furthermore, the FTIR studies of the complex demonstrate coordination of Th(IV) with SSA, phen, and nitrate by the participation of oxygen and nitrogen atoms. According to the results obtained, the changes in the IR spectra indicate that the coordination takes place via nitrogen atoms of phen, oxygen atoms of SSA and nitrate ions, the former two acting as bidentate ligands while as the latter coordinate via the monodentate mode. Moreover, from the emission spectra, the complex also showed emission atom excitation wavelength of 290 nm.
