 note = {The complex formation of non-cyclic linear polyoxyethylenes and their alkyl derivatives (POE compounds) and application to analytical chemistry are reviewed. The POE compounds form the complexes with alkali and alkaline earth metal ions in the same manner as the cyclic one (crown ether). Although the selectivity and stability of the complex formation are inferior to that of crown ether, POE compounds are interesting material because they have flexible structure and the compounds having a very long ethylene oxide (EO) unit are available. The structures of the crystalline complexes have been determined as the metal ion is surrounded by EO moieties and similar structures are estimated for the complexes in solution. Generally they form 1 : 1 complexes with a metal ion. In case of long chain POE compounds, however, polynuclear complexes are formed. POE compounds are widely used as non-ionic surfactants (NIS). The complexation of POE compounds has been applied to various separation and determination methods, such as solvent extraction, trace analysis of NIS and metal ions and so on. Peculiar properties of POE compounds as NIS have been also utilized for various analytical methods.},
