The reaction of these ligands with [(p-cymene)RuCl2]2 or [(C6H5CH2NMe2H)RuCl2]2Cl2 resulted in the formation of 12-metallacrown-3 complexes, which possess strong affinity for lithium ions. By a judicious choice of the fluorophore and the arene -ligand, a macrocycle was obtained that could be used in aqueous solution to selectively and quantitatively detect lithium ions by fluorescence spectroscopySupramolecular Triangular HostsAmyotrophic-Lateral-Sclerosis12-Metallacrown-3 ComplexesAlzheimers-DiseaseLi+SensorRecognitionFluoroionophoreExtractionStabilityRuthenium-based metallacrown complexes for the selective detection of lithium ions in water and in serum by fluorescence spectroscopytext::journal::journal article::research article
