“…MnO 4 − is another strong oxidant that extensively used both in industry and laboratories . Besides, it can also be applied to treating polluted water and fish diseases as disinfection and antiseptic in low concentration . Indeed, MnO 4 − is also very harmful to human health and can lead to gastrointestinal disorders, skin, respiratory infection, liver and kidney damage and even deformity .…”

Due to their striking opticalp roperties, luminescent coordination polymers as sensors for the detection of hazardous species have drawn interest of researchers in consideration of the control of environmental pollution. In this work, the organic ligand 2-(4-((E)-2-(pyridine-2-yl)vinyl)styryl)pyridine (2-bpeb),w hich possesses al arge p-conjugated system, was employedt or eact with d 10 metal ions to obtain novel luminescentc oordination polymers. Three complexes [Cd(2-bpeb) 0.5 (CNA)(H 2 O)] (CP1), [Cd(2-bpeb) 0.5 (NDC)] (CP2) and [Zn(2-bpeb)(BDC)] (CP3)w ere synthesized successfully by introducing carboxylic acids of 4-carboxycinnamic acid (H 2 CNA), 2,6-naphthalene dicarboxylica cid (H 2 NDC) and 1,4benzenedicarboxylica cid (H 2 BDC) as auxiliary ligands. Because of the existence of the large p-conjugated system and d 10 metal ions, all of these coordinationp olymers exhibit striking fluorescencep roperties.I mpressively,a ll of them can functiona ss ensors for the detection of highly oxidizing anionsM nO 4 À and Cr 2 O 7 2À ,w ith an increased sensitivity for MnO 4 À .Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

“…Over the past few years, many luminescent coordiantion polymers have been synthesized to detect metal ions, anions, pH value, small molecules, gases and vapors (Kurmoo, 2009;Lan et al, 2009;Li et al, 2013;Ma et al, 2013;Zhang et al, 2015;Yu et al, 2017;Mi et al, 2019;Tang et al, 2020), in this contribution, we select a tricarboxytriphenylamine (H 3 L) as a ligand to construct a new Co coordiantion polymer is mainly based on the following considerations: 1) The conjugated and photoactive triphenylamine moiety makes the MOFs highly fluorogenic; 2) Lewis base N sites on the internal surface of the framework can improve the sensing of ions and adsorption of CO 2 ; 3) The carboxylate groups have multiple coordination modes to coordinate the metal ions, and the uncoordinated O atoms can provide interaction sites for the metal ions and NACs (specifically, TNP containing three NO 2 groups). Meanwhile, among the MOF sensors, highly economical and abundant Co. ions with magnetic properties have rarely been studied as sensors, mainly because the non-d 10 electronic structures have low emission performance owing to d-d transitions (Mishra et al, 2014;Chen et al, 2017;Zhao et al, 2018).…”

A 3D supermolecular structure [Co3(L)2 (2,2′-bipy)2](DMF)3(H2O)3 1) (H3L = 4,4′,4″-nitrilotribenzoic acid) has been constructed based on H3L, and 2,2′-bipy ligands under solvothermal conditions. Compound 1 can be described as a (3, 6)-connected kgd topology with a Schläfli symbol (43)2(46.66.83) formed by [Co3(CO2)6] secondary building units. The adsorption properties of the activated sample 1a has been studied; the result shows that 1a has a high adsorption ability: the CO2 uptakes were 74 cm3·g−1 at 273 K, 50 cm3·g−1 at 298 K, the isosteric heat of adsorption (Qst) is 25.5 kJ mol−1 at zero loading, and the N2 adsorption at 77 K, 1 bar is 307 cm3 g−1. Magnetic measurements showed the existence of an antiferromagnetic exchange interaction in compound 1, besides compound 1 exhibits effective luminescent performance for Fe3+/Cr3+ and TNP.

Effective detectiono fo rganic/inorganic pollutants, such as antibiotics, nitro-compounds, excessive Fe 3 + and MnO 4 À ,i sc rucial for human health and environmental protection. Here, an ew terbium(III)-organic framework, namely [Tb(TATAB)(H 2 O)]·2H 2 O( Tb-MOF,H 3 TATAB = 4,4',4''-s-triazine-1,3,5-triyltri-m-aminobenzoic acid), was assembled and characterized.The Tb-MOF exhibits awater-stable 3D bnn framework. Due to the existence of competitive absorption, Tb-MOF has ahigh selectivity for detecting Fe 3 + ,MnO 4 À ,4-niro-phenola nd nitroimidazole( ronidazole, metronidazole, dimetridazole, ornidazole) in aqueous through luminescent quenching. The results suggest that Tb-MOF is as imple and reliable reagent with multiple sensor responses in practical applications. To the best of our knowledge, this work represents the first Tb III -based MOF as an efficient fluorescent sensorf or detecting metal ions, inorganic anions, nitro-compounds, and antibiotics simultaneously.[a] J.
