Abstract
New derivatives of azobenzene crown ethers have been obtained. They include compounds with alkyl, alkoxy, hydroxy or dimethylamino group in aromatic residue(s) as side substituents. Their chromoionophoric properties and properties in ion-selective membrane electrodes have been studied. Structures of two azocrown ethers with peripheral hydroxy group in benzene ring were confirmed by X-ray analysis. Effect of metal ion complexation by hydroxyazobenzocrown ethers on hydroxyazo-quinone hydrazone tautomerism was studied.
