  Study of the structure of solutions of the H-complexes of diesters of tetracarboxylic acids with diamines by the light scattering method 1. H-complex of the dimethyl ester of benzophenonetetracarboxylic acid with hexamethylenediamine

  摘要：

  Conclusions about structure formation in solutions of the H-complexes of benzo-phenonetetracarboxylic acid with hexamethylenediamine have been drawn from the angular dependence of the intensity of scattered polarized light. The calculated statistical structural parameters show that the H-complexes form dipentameric associations. At high concentrations of the complexes in aqueous-methanolic solution the supermolecular structure is disrupted, while in the pure alcohol the reverse process is observed.
