Abstract: The equilibrium constants of complexes of 7 purine derivatives with
1,5-naphthalenediol and of 5 purine derivatives with 1-naphthol were established in aqueous solutions at 20°C by using electron absorption spectrometry.
The study of interactions has shown that the equilibrium constants of the
complexes of the studied purines with 1,5-naphthol are generally higher
than those of the complexes with 1-naphthalene and that the presence of
further methyl and oxo groups, respectively, in the purine molecule results in
significant increase of equilibrium constants of the formed complexes.
