A heterometallic sodium–europium-cluster-based metal–organic framework as a versatile and water-stable chemosensor for antibiotics and explosives

Abstract

A stable luminescent MOF, constructed from a novel Eu2Na cluster and tricarboxylate, has been synthesized into a cubic framework and demonstrated to be the first known MOF for the selective detection of ornidazole antibiotics.

A Water‐Stable Uranyl Organic Framework as a Highly Selective and Sensitive Bifunctional Luminescent Probe for Fe3+ and Tetracycline Hydrochloride

“…[7,8] Therefore, the detection and sensing of antibiotic molecule and Fe 3 + are of great significance in the fields of medicine, agronomy,l ife science and environmentals cience.

White-Light-Emitting Decoding Sensing for Eight Frequently-Used Antibiotics Based on a Lanthanide Metal-Organic Framework

“…The eight antibiotics@ 4 hold the minimal LOD order of NZF > SDZ > TC > CBZ > DTZ > MDZ > NFT > ODZ. According to Table 1, the K SV and LODs of antibiotics@ 4 in this contribution are far superior to most reported fluorescence probes for these antibiotics [42,48,49,50,51,52,53,54], and meets the standard of U.S. Environmental Protection Agency and World Health Organization for the maximum allowable level of antibiotics in drinking water (Table 1) [5,55]. Additionally, we find that complex 4 can be regenerated and reused for a significant number of cycles by centrifugation of the solution after use and washing several times with water.…”

A new antiferromagnetic Dy6 oxido-material as a multifunctional aqueous phase sensor for picric acid as well as Fe3+ ions

“…From the linear fitting of the plot, the quenching constant for PA was found to be 3.5 × 10 8 , which indicates the super quenching ability of 1 towards PA in water. To the best of our knowledge, this is one of the highest quenching constant values for any OM among the reported POMs as well as MOFs for selective sensing of PA to date [6,21,59]. The behaviour of interaction (whether static or dynamic) between OM and analytes, can be anticipated by (i) analysing the absorption spectral changes of OM by the addition of analytes, (ii) time-resolved measurements of photoluminescence decays of the OM after addition of analytes.…”
