“…Recently, most of studies in the field of photoluminescence properties of Ln(III) complexes have been focused on Eu(III), Tb (III), Dy(III) and Sm(III) compounds [16][17][18][19][20][21][22][23]. Since, emission from Ho(III) complexes is rare as their electronic structure is susceptible to non-radiative deactivation.…”

“…But the real life application demands the pesticide detection in aqueous medium as the agricultural runoff and other source of pesticide toxicity may enter into the living system through aquatic environment. For this purpose, Zhang and coworkers synthesized two MOF {[Eu(DSPT)(ox) 0.5 ]⋅H 2 O} n and {[Tb(DSPT)(ox) 0.5 ]⋅H 2 O} n {where H 2 DSPT=4′‐(2,4‐disulfophenyl)‐2,2′:6′2′′‐terpyridine and ox=oxalate} for the first time luminescence quenching based detection of diethyl chlorophosphate (DCP) in aqueous medium . They have claimed that the phosphorylation of the terpyridine nitrogen atoms by DCP is able to destroy the antenna effect, as a consequence the energy transfer from the ligand centre to the metal centre (Eu/Tb) will be stopped resulting the quenching of luminescence intensity.…”

A new metal-organic framework (MOF) [Cd 2.5 (PDA)(tz) 3 ] {PDA = 1,4-Phenylenediacetate and tz = 1,2,4-triazolate}, 1, has been synthesized by solvothermal reaction. The structure and morphology of 1 was systematically characterized by Powder X-ray diffraction (PXRD), Single crystal X-ray diffraction (SCXRD), Thermogravimetric analysis (TGA), Infrared spectroscopy (IR) and Field emission scanning electron microscopy (FESEM). Single crystal X-ray data of 1 confirmed cage connected threedimensional structure with three different types of Cd 2 + ions (square pyramidal, trigonal antiprism and octahedral geometries). Photoluminescence study of 1 in aqueous medium showed emission at 290 nm upon excitation at 225 nm. This emissive property was used for the highly selective and sensitive detection of azinphos-methyl pesticide in aqueous medium through luminescence quenching. Compound 1 is able to detect azinphos-methyl with a detection limit of 16 ppb and its sensitivity remains unchanged in the presence of other pesticides.

Organophosphorus chemical warfare agents (OP CWAs) are potent acetylcholinesterase inhibitors that can cause incapacitation and death within minutes of exposure, and furthermore are largely undetectable by the human senses. Fast, efficient, sensitive and selective detection of these compounds is therefore critical to minimise exposure. Traditional molecular-based sensing approaches have exploited the chemical reactivity of the OP CWAs, whereas more recently supramolecular-based approaches using non-covalent interactions have gained momentum. This is due, in part, to the potential development of sensors with second-generation properties, such as reversibility and multifunction capabilities. Supramolecular sensors also offer opportunities for incorporation of metal ions allowing for the exploitation of their unique properties. In particular, trivalent lanthanide ions are being increasingly used in the OP CWA sensing event and their use in supramolecular sensors is discussed in this Minireview. We focus on the fundamental interactions of simple lanthanide systems with OP CWAs and simulants, along with the development of more elaborate and complex systems including those containing nanotubes, polymers and gold nanoparticles. Whilst literature investigations into lanthanide-based OP CWA detection systems are relatively scarce, their unique and versatile properties provide a promising platform for the development of more efficient and complex sensing systems into the future.
