Highly efficient fluorescent chemosensor for nitro antibiotic detection based on luminescent coordination polymers with 2,6-di(4-carboxyphenyl)pyrazine

Abstract

As a hot-spot issue of global concern, antibiotics' overuse poses a significant threat to the eco-environment and human health. Here, three isostructural coordination polymers with the formula {[M(DCPP)(H2O)]∙(DMF)}n [M =...

Hydrogen-Bond-Connected 2D Zn-LMOF with Fluorescent Sensing for Inorganic Pollutants and Nitro Aromatic Explosives in the Aqueous Phase

“…It is worth mentioning that JLU-MOF109 exhibits a similar structure to [Zn(DCPP) (H 2 O)]• (DMF). 52 The experimental PXRD pattern of JLU-MOF109 can match well with the simulated one, which indicates the phase purity of the as-synthesized product (Figure S2).…”

Ultrasensitive fluorescence detection of norfloxacin in aqueous medium employing a 2D Zn(ii)-based coordination polymer

“…Sun et al reported three CPs for the detection of nitro antibiotics through the fluorescence quenching effect. 21 Fu et al synthesized two CPs that can selectively identify levofloxacin (LVX) with high sensitivity. 22 Zhou et al demonstrated that a robust zirconium-based MOF can serve as a sensor to detect tetracycline (TC) in water.…”

Two fluorescent copper phosphonate complexes for sensing antibiotics, ketones and Fe3+ in water

“…The large amount of sewage discharged from livestock farms, hospitals and antibiotic production plants not only affects water quality, but also produces more resistant bacteria, which indirectly affects human health. [23,46] We selected nine of the most commonly used antibiotics to explore the potential application of complexes 1 and 2 in the rapid and effective detection of antibiotics. The molecular formulas of the nine selected antibiotics list in Figure 8.…”

“…[15][16][17][18][19][20] The hybrid properties endowed by the metal and ligand also make it a promising candidate as fluorescence sensors to detect specific species. [21][22][23][24] In the past several years, our research group has been working on bifunctional anionic units as building blocks to construct new complexes with fascinating structures and intriguing properties. [25][26][27][28] At present, in the exploration of phosphonate complexes, some bifunctional or multifunctional ligands such as aminophosphonates or phosphonocarboxylates have been adopted due to their versatile coordination ability.…”
