Abstract

The identification and quantification of different pollutants in aquatic and biological systems with chemosensors have received a lot of attention in analytical chemistry. Chemosensors are becoming more and more popular due to their benefits, which include excellent selectivity and sensitivity, low cost, ease of use, simpler equipment, and quick turnaround times. Additionally, quinoxaline-based derivatives possess excellent photophysical properties among other heterocyclic compounds, and therefore have been deployed in chemosensors for colorimetric and fluorimetric detection of various chemical species. This review summarizes literature from 2018 to 2024, focusing on quinoxaline derivatives used to detect cations, anions, and neutral small molecules. The highlights on an overview of a chemosensor, the structure of analyte recognition unit, recognition mechanism, detection limits, binding stoichiometry, and formation constants are clearly delineated. Practical applications of these chemosensors in solution or solid phases are also discussed. Researchers can use this information to develop effective, sensitive, and selective chemosensors utilizing quinoxaline derivatives for the analysis of cations, anions, and neutral molecules under physiological, organic and aqueous settings.

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.
