Oligoether derivatives of 1-phenoxyanthraquinone: Synthesis, photochromism, and complex formation with metal cations

1-Phenoxyanthraquinone isomeric conjugates with tetraethylene glycol were prepared. Their photochromic properties and complex formation in solutions were quantitatively studied by spectrophotometry, quantum yields of the arylotropic photoisomerism and stability constants of complexes between para–ana-quinoid isomers and metal cations. The photochemical migration of a phenyl group considerably affects the complex stability thus providing the possibility to regard the synthesized compounds as photocontrolled ionophores. The structure of some complexes was investigated by X-ray diffraction (XRD) analysis and quantum-chemical simulation.

Nucleophilic substitution in the l-nitro-4-chloroanthraquinone by phenolates and thiophenolates

In reactions of l-nitro-4-chloroanthraquinone with phenolate anions first is chiefly substituted the chlorine atom, whereas by the thiophenolate anion predominantly is replaced the nitro group. The difference in behavior with this substrate of the O- and S-nucleophiles is attributed to the change in the proportion of electrostatic and orbital interaction.

Reaction of 1-Fluoro-4-nitroanthraquinone with O-, S-, and C-Nucleophiles

Reactions of 1-fluoro-4-nitroanthraquinone with O-, S-, and C-nucleophiles, regardless of the nature of the anionic center, result in replacement first of the fluorine atom.
