Dual-emitting dye-CDs@MOFs for selective and sensitive identification of antibiotics and MnO₄⁻ in water

Abstract

The “smart” fluorescent material RhB-CDs@1 contains functions of multicomponent recognition, including the detection of quinolones, tetracyclines, nitrofurans and MnO4− in aqueous solution.

State of the art methods and challenges of luminescent metal–organic frameworks for antibiotic detection

“…Zhu et al synthesized a novel dual-emissive ratio luminescent probe based on RhB-CDs@MOF (CDs = carbon dots) for antibiotic detection. 118 Unlike other dye@MOFs, this sensing composite can be prepared by post-synthetic modification. As illustrated in Fig.…”

Carbon Dots in Porous Materials: Host–Guest Synergy for Enhanced Performance

“…[25] As for MOFs with smaller pore size than CDs,post-modification method by utilizing agglomerant to bond CDs onto the surface of MOFs is more feasible. [26] Note that different from CDs@zeolites,o ne-step synthetic method is not general for CDs@MOFs because the precursors of CDs would influence the crystallization of MOFs and the synthesis temperature of MOFs is usually lower than the carbonization temperature of CDs. [27]…”

Three Zn(II) coordination polymers as dual‐responsive luminescent probes for highly selective detection of Fe3+ cation and MnO4− anion

“…[5][6][7][8][9] Besides cations, there are some anionic pollutants, such as MnO 4 À , it has also became the important factor of water pollution due to its widely application in drinking water treatment. [10] So searching for efficient detection methods on these ion pollutants is extremely essential. Up to now, high performance gas-liquid chromatography, mass spectrometry, and potentiometric methods are the most commonly used traditional detection methods, but these methods have the disadvantages of inconvenience, timeconsuming, and large investment.…”

“…À with excellent performances. [1,15,[32][33][34][35] Next, the anti-interference ability of LCPs 1-3 was studied.…”
