Alluminium complexes for biomedical applications
Beranová, Tereza ; Kubíček, Vojtěch (advisor) ; Havlíček, David (referee)
The aim of this work was to prepare ligands of macrocycle TACN with aminophosphinate pendant arms. Two ligands were prepared and fully characterized. A complex of aluminium ion was synthesized with one of the ligand. The complex was used for studying a fluoride coordination by a fluoride ion selective electrode. Key words: macrocyclic complex, positron emission tomography, phosphinic acid

TACN derivatives bearing aminophosphinate pendant arms
Beranová, Tereza ; Kubíček, Vojtěch (advisor) ; Němec, Ivan (referee)
The aim of this work was studying of the coordination properties of TACN macrocyclic derivatives with aminophosphinate pendant arms. Two ligands were prepared, one with two pendant arms NODPam and one with three pendant arms NOTPam. Because of degradation of ligand NODPam during its synthesis, only the ligand NOTPam was studied further. Acid-base properties of ligand and termodynamic stability of aluminium and gallium complexes were studied. Formation and disociation studies were performed with the complexes. Coordination of fluoride ions to aluminium complex was studied using ion selective fluoride electrode. Finally coordination of complex AlFx with ligand NOTPam was studied using 19F and 27Al NMR spectroscopy. Selected experiments were made also with ligand NOTA. Key words: macrocyclic complexes, positron emission tomography, phosphinic acids

Macrocyclic ligands for selective complexation of large cations
Šefčík, Martin ; Kotek, Jan (advisor) ; Vojtíšek, Pavel (referee)
4 Abstract Nowadays, macrocyclic complexes of actinides receive an increasing attention for their potential applications in radiotherapy. It requires significant demands on their thermodynamic and kinetic stability which are particularly influenced by an appropriate choice of a ligand. This Thesis focuses on a synthesis and characterization of two ligands that are potentially applicable for complexation of lanthanum as a model of radioactive actinium. Both ligands are based on a fifteen-membered cycle containing pyridine group, 15-pyN3O2. The first ligand, H4L1, contains two phosphonate pendant arms. The second ligand, H2L2, contains two phosphinate pendant arms. Both compounds were prepared and characterized. Keywords Macrocyclic ligands, large cations, phosphonic acids, phosphinic acids, dissociation constants
