Complexformation properties of new crown-containing 1-hydroxyanthraquinone imines with donor and acceptor substituents in the anthraquinone nucleus were studied. The compounds were prepared by photochemical reactions of 4-aminobenzo-15-crown-5-ether with photoactive derivatives of 1-phenoxyanthraquinone. It has been established that the introduction of acceptor substituents causes a shift of the prototropic
