Abstract in another language

In the present work three different research projects regarding the functionalization and self-assembly of gold nanoparticles (AuNP) with functional block copolymers of
styrene and 4VP (S4VP) in solution were presented. S4VP block copolymers with different block lengths of 4VP were synthesized via sequential living anionic polymerization. Two different approaches of functionalized AuNP with S4VP polymers were exposed. Pyridylterminated polystyrenes were employed as monodentate ligands for AuNP, while longer
blocks of 4VP were used as multidentate ligands. The control of selectivity and distribution of metal nanoparticles within the S4VP block copolymer domains were probed by two different methods, namely ligand exchange reactions and in situ reactions of AuNP by reduction of a metal salt with NaBH4. The optical properties of these S4VP/AuNP nanocomposites were thoroughly studied.

Abstract in another language

Im Rahmen dieser Arbeit wurden drei verschiedene Forschungsprojekte hinsichtlich der Funktionalisierung und Selbstanordnung, oder sogenannten „Self-Assembly“ von Goldnanopartikeln (AuNP) mit funktionalen Blockcopolymeren aus Styrol und 4-Vinylpyridin (S4VP) durchgeführt. S4VP Blockcopolymere wurden mittels lebender anionischer Polymerisation hergestellt. Durch Steuerung des 4VP Blocks fungieren diese als monodentate bzw. multidentate Liganden für AuNP. Sowohl die Kontrolle und Selektivität
der AuNP Verteilung als auch die optischen Eigenschaften des S4VP/AuNP Nanokomposit Materials wurden sorgfältig untersucht. Desweiteren wurde ein telecheles alpha-OHS4VP
hergestellt. Dabei wurde die Methode der anionischen Polymerisation angewendet.
