“…Wang and co-workers synthesized Ru(II) complex 42 ( Figure 5 ), encompassing both imidazole and indole groups, which acted as selective and naked eye detectors of CH 3 COO − at much lower concentrations as compared to other anions such as H 2 PO 4 − , I − , Br − , Cl − , F − , and NO 3 − [ 79 ]. Free receptor showed two absorption bands at 291 nm (bpy-based π-π*) and at 462 nm ( 3 MLCT band), which gradually decreased upon sequential addition of CH 3 COO − to 42 along with a notable amplification of the absorption band at 346 nm with the onset of an isosbestic point at 376 nm and a new peak at 430 nm.…”

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.

“…In particular, ruthenium(II) polypyridyl complexes have attracted wide attention attributable to the usefulness in many fields of applications such as catalysis (Kunz et al 2012;Małecki et al 2013), sensors (Gao et al 2012;Yang et al 2010), liquid crystals (Cardinaels et al 2009) and DNA binding (Jing et al 2004;Kumar et al 2010;Li et al 2011;Liu et al 2010aLiu et al , 2010bZhang et al 2004). The studies on the binding of Ru(II) complexes with DNA have become prominent recently, investigating the binding mode either reversible or non-covalent.…”

Functionalized Ruthenium Complexes: Selective “Turn‐on” Detection of Biologically Relevant Anionic Species

et al. 2017

To study the effect of the structure of 3,3′‐modified bipyridyl ruthenium complexes on their ability to recognize organic anions, various ruthenium complexes have been prepared. The binding functions and large‐sized modified bipyridyl ligand turned out to be essential for selectivity in acetonitrile. The selectivity for dicarboxylates or phosphates can be switched by using guanidinium‐ or ammonium‐functionalized probes. One of these probes turned out to be selective towards glutamate over aspartate and γ‐aminobutyric acid (GABA). Another was selective towards adenosine 5′‐triphosphate (ATP) over adenosine 5′‐diphosphate (ADP), pyrophosphate (PPi), adenosine 5′‐monophosphate (AMP), and orthophosphate (Pi). In both cases, the binding was attributed to coulombic interactions and hydrogen bonding. π‐stacking interactions also occurred with nucleotides. Replacing ammonium by zinc‐dipicolylamine units made possible the recognition of phosphorylated species in buffered aqueous systems. To our delight, this probe showed selectivity for ADP over ATP and we proved that the selectivity was partly due to substitution at the 3‐ and 3′‐positions of the ligand.
