Abstract

Polymer metal-organic framework (MOF) are a new class of hybrid porous materials that combine the advantages of both organic polymers and metal-organic frameworks. In this regard, a new ligand was synthesized - a hyperbranched polyester polybenzoylthiocarbamate, the structure of which was established by IR, 1H NMR, electron spectroscopy and elemental analysis. Complexing properties have been studied using the example of Cu(II) and Co(II) ions. The formation of metal-polymer clusters with metal ions with the participation of benzoylthiocarbamate groups of the polyester has been proved by IR, electron spectroscopy and electron microscopy. It was found that the structure of coordination sites is octahedral with tetragonal distortions. The compositions and conditional logarithms of the stability constants of the complexes were determined.
