First Time

New crown-containing imines of 1-hydroxyanthraquinone with chlorine and fluorine atoms in the anthraquinone nucleus were synthesized. For the first time, the thermal and photochemical stages of synthesis are carried out in the solid state (without a solvent). The features of complexation of new chemosensors with cations of alkaline and alkaline earth metals were studied by spectrophotometry. It is shown that the introduction of halogen atoms in the anthraquinone nucleus leads to a significant spectral response. The obtained compounds are tested as components of test systems for visual determining the presence of alkaline earth metal cations in aqueous media.
