Recent advancements in the detection of hazardous metal ions using rhodamine-based chemosensors

Recent advancements in the detection of hazardous metal ions using rhodamine-based chemosensors
Rhodamine-based chemosensors have emerged as a prominent class of sensors for detecting harmful metal ions due to their excellent photophysical properties, such as high fluorescence quantum yields, large absorption coefficients, and strong fluorescence emission. This review comprehensively summarizes recent advances in the design, synthesis, and application of rhodamine-based chemosensors, specially fluorescent chemosensor, emphasised on the molecular structure, detection target ions, detection mechanism, detection limit, detection solution system, and performance of the rhodamine-based chemosensors. It highlights the mechanisms underlying their operation, including photoinduced electron transfer (PET), fluorescence resonance energy transfer (FRET), and ring-opening processes. This review has been classified by target harmful metal ions, such as Hg2+, Pb2+, Cd2+, Cr3+, Cu2+, Ni2+ and Zn2+. By improving the selectivity, sensitivity, and stability of these sensors, recent advancements address problems including environmental stability and interference from other ions. Furthermore, the range of detection in complicated environmental samples has increased with the introduction of novel functionalised rhodamine derivatives and hybrid sensor systems. The integration of rhodamine-based chemosensors into useful applications for tracking toxic metal ions in soil, water, and biological systems This critical review highlights the opportunities and obstacles for future research and innovation in the development of more sensitive, selective, and robust rhodamine-based chemosensors for the detection of hazardous metal ions.

期刊介绍: Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
