Abstract

The analytical methods are approached in three ways: (i) detection and quantitation of specific metal phenolates, especially the simpler ones used in industry; (ii) methods of detection and quantitation involving selective formation of a complex of the analyte with a phenolic ligand, taking advantage of special properties of the complex (optical, luminescent, electrochemical, phase transfer, etc.); (iii) certain metal–phenolate complexes act as analytical tools, specifically interacting as hosts with the analyte or by interchanging the metal ions and undergoing changes of properties (optical, luminescent, electrochemical, etc.) that can be applied to detection or quantitation. Although in approaches (ii) and (iii) the main subject is selective metal cation recognition, some attention is also paid to selective recognition of anions and molecules. For completeness of the analytical methods covered by phenolic reagents or complexes, specific recognition of ammonium ions, and especially quaternary ammonium ones, is discussed in a special section.
