New polypyridine anchoring ligands for coordination complexes and surface functionalization

This PhD thesis focuses on the synthesis of new polypyridine anchoring ligands and several dfferent
applications. The ligands consist of a coordinating part, a flexible linker and an anchoring group.
Due to the fact that different anchoring groups were used, the ligands can be applied for several
types of surface-materials. Using these anchoring ligands, several coordination complexes were
synthesized. Ruthenium-based complexes, bearing an ion-sensitive ligand, were tested towards their
sensing properties. The photophysical properties of luminescent Ir(III)-complexes were investigated
and compared to related compounds. Furthermore, different types of materials were functionalized
with the coordinating anchoring ligands and characterized.
Chapter 1: Introduction
Chapter 1 gives background information about the different topics where the synthesized ligands
and complexes can be applied.
Chapter 2: coordination anchoring ligands
Here, the synthesis of the anchoring ligands is presented. The photophysical properties and an X-ray
structure are discussed.
Chapter 3: Complexes for detection
In this chapter, the synthesis and the photophysical properties of several ruthenium complexes are
described. Titration experiments and sensing tests are described and the results are discussed.
Chapter 4: Surface functionalization
Chapter 4 shows different applications for the synthesized ligands. Functionalization of different
surfaces is described as well as their photophysical characterization. Also the synthesis and the photophysical
properties of luminescent Ir(III) complexes, bearing an anchoring ligand, are presented.
Chapter 5: Diverse other ligands
The synthetic routes for two DSSC anchoring ligands are shown in chapter 5. Furthermore, the
syntheses of solvatation ligands for quantum dots and for a novel detection ligand are described.
