Title: Ligands for Multifunctional Dinuclear Complexes Author: Marie Králová Site: Charles University in Prague, Faculty of Science Supervisor: doc. RNDr. Pavel Vojtíšek, CSc. Abstract The aim of this work was to prepare substitued phenols as ligands for binuclear complexes of copper(II), which could be used as anion receptors. Two main sythethic strategies are summarised in the introduction: First is single step Mannich-type reaction of 4-substitued phenol, paraformaldehyde and secondary amine, other includes preparation of substitued bis(halomethy)phenol and it's following reaction with secondary anime. A single step Mannich-type reaction was used for preparations of following known ligands: 2,6-bis[(N-methyl piperazine-1-yl)methyl]-4-formyl phenol (L1), 2,6-bis[(N- methyl piperazine-1-yl)methyl]-4-nitro phenol (L3) and 2,6-bis[(N-phenyl piperazine-1- yl)methyl]-4-nitro phenol (L4). The new ligand, 2,6-bis[(N-phenyl piperazine-1-yl)methyl]- 4-formyl phenol (L2), was prepared in the same way. A structure of this ligand was determined using X-ray. One Pd(II) complex [PdL2Cl2]·1.5MeCN (K3) was prepared and it's structure was determined. UV-VIS spectroscopy was used to study interactions in ligand - metal and ligand - metal - anion systems in order to determine the anion - binding capabilities of the...
