Abstract

The synthesis of metal containing nanoparticles have been widely studied during the last decades. These compounds display properties that can be easily varied to adapt to finely selected conditions. This makes them suitable for applications such as catalysis and medicine.
The goal of this project is the synthesis of a water-soluble polymer made of a one-step synthetic bipyridine-derivative monomer as well as the study of its ability to interact with palladium(II) salts to form particles.

For this, the optimization of the synthesis of the monomer 1-(4-vinylbenzyl)-[4,4’-bipyridin]-1-ium chloride has been developed. This monomer has been polymerized together with acrylamide in order to enhance the water solubility of the final polymer.
The Kelen-Tüdos method has been performed in order to investigate the polymer conformation. The resultant polymer has been characterized using techniques such as GPC, 1H NMR and DLS.

Finally, the interaction between the copolymer and a precursor palladium complex has been studied. For this, UV-Vis and 1H NMR experiments have been performed in order to study the interactions between monomer and palladium centers as well as polymer palladium. In addition, DLS has been used to study the effect of the addition of the metal to a polymer solution in the particles size.
