Selective complexation of transition metals ions
Beliš, Marek ; Kotek, Jan (advisor) ; Vojtíšek, Pavel (referee)
Copper radionuclides possess physical properties suitable for utilization in nuclear medicine. Important part of their preparation is separation from mother elements, usually zinc or nickel. Currently used methods of separation have their limits, what opens field for finding new ways. One part of the Thesis contains preparation of simple ion exchangers and their selectivity study. The other part of the Thesis is dedicated to optimization of synthetic steps leading to new bifunctional ligands in suitable form for binding to macromolecular carriers and preparation of new set of exchangers.
Reactivity and properties of triphosphate analogues
Šrein, Jakub ; Kubíček, Vojtěch (advisor) ; Vojtíšek, Pavel (referee)
Reactions leading to cyclization on methylene bridges in PCPCP structure motif were investigated. It was found, that these reactions result in number of various isomers. Some of these isomers were characterized by NMR and MS spectroscopy, but none was isolated. Further, acid-base properties of bis(methylenephosphonato)phosphineic acid were investigated. Formation of complexes was studied with lithium(I), calcium(II), copper(II) and zinc(II) cations. Furthermore, interaction between bis(methylenephosphonato)phosphinic acid and ethylenediamine was investigated by NMR and potentiometric titration. The results show formation of H-bond-based adducts.
