摘要: Complex formation properties of new crown-containing 1-hydroxyanthraquinone imines with donor and acceptor substituents in the anthraquinone nucleus were studied. The compounds prepared by photochemical reactions 4-aminobenzo-15-crown-5-ether photoactive derivatives 1-phenoxyanthraquinone. It has been established that introduction causes a shift prototropic tautomeric imine-enamine equilibrium towards NH-form. As result, significant cation-induced spectral changes are observed during complex formation.
