Abstract:
In supramolecular chemistry, the design and synthesis of anion receptors has a long tradition, stemming from the fact that many biologically important structures as well as environmental pollutants have the nature of anions. Although a number of highly selective and effective anion receptors have been developed in recent years, work on their practical applicability is not very common. This project aims to design and synthesize receptors anchored to dendrimers. This connection of the sensory part with the bulky dendritic part promises not only the multiplication of binding sites, but also easy separability of the formed complexes from the solution, eg by nanofiltration methods. This fact should make it possible to separate, for example, phosphates or carboxylates from the aqueous medium or to separate the enantiomers of medically important substances. It is also envisaged to develop a methodology for recycling the receptors used for these separations.
