STRUCTURE AND STRUCTURAL TRANSFORMATIONS OF MACROMOLECULES WATER-SOLUBLE POLYMERS AND LUMINESCENCE OF MAGNESIUM SALT OF 8-ANILINENAPHTHALENE-1-SULFONIC ACID

We established the molecular mechanism for influence of the chemical s tructure of water-soluble polymers and structural transformations of m acromolecules on luminescence of the magnesium salt of 8-anilinenaphth alene-1-sulfonic acid (ANS) in aqueous solutions. It is shown, that lu minescence of ANS in polymer solution is mainly determined by ANS inte raction with proton-accepting groups, that are not bound to proton-don ating groups of macromolecular environment, or by ANS interaction with positively charged polymer groups. The variation of luminescence with increasing content of non-polar groups in polymer is insignificant, a nd takes place only in the presence of aforementioned interactions.
