Macro-inorganics. Part 6. Protonation and complex formation of a new series of polymers whose repeating units behave independently

Abstract

The protonation and copper(II) complex formation of some new polymers with a poly(amido-amine) structure has been studied in aqueous solution by potentiometric, calorimetric, and spectroscopic techniques. The polymers are characterized by the fact that no ring structures are present along the main chain between tertiary amino-groups of different units. The results indicate the monomeric units of this new family of poly(amido-amines) behave independently towards both protonation and complex formation. Comparison with previously studied poly(amido-amines) shows that the presence of linear diamide moieties in place of 1,4-diacylpiperazine rings [as in the previously studied poly(amido-amines)] has a slight influence on the protonation constants, although differences may be observed in the thermodynamic functions ΔH and ΔS. Significant differences are observed in copper(II) complex formation.
