Ligandové systémy pro komplexaci zirkonia / Ligand systems for zirconium complexation

The aim of this thesis is to synthesize new kind of macrocyclic ligands for complexation of Zr4+ . Zirconium(IV) complexes have potential as contrast agents in immuno-PET. Three macrocyclic ligands L1, L2 and L3 with dif- ferent pendant arms (HOPO, maltol, hydroxamate) were designed. Despite numerous attempts syntheses of L1 and L2 were unsuccessful. Ligand L3 was synthesized and the protonation constants were determined by poten- tiometric titration. Complexes [Zr4+ (L3)] were studied too. Catechol ligand L4 was prepared and complexes with cations Zn2+ , Ga3+ and Zr4+ were investigated. 1
