SFB 858 B15 - Innovative Ligands at Nanoparticles and at Surfaces

Basic data for this project

Description

Within this collaboration innovative carbene and thioether ligands are developed that bind to nanoparticles and surfaces. An efficient ligand exchange protocol allows the generation of novel carbene functionalized nanoparticles, that shall be tested in e.g. asymmetric catalysis. The nanoparticle synthesis does not involve the stabilization of the particles by N-heterocyclic carbenes, being one of the advantages of this new method that allow the synthesis of a variety of functionalized nanoparticles and lead to more stable particles. These libraries shall be synthesized, characterized and applied in catalytic test reactions. Furthermore we have shown, that specific thioether ligands with bioxazoline moiety generate stable monolayers at gold surfaces. It has to be shown, that this special metal ion arrangement at the metal surface influences the hybrid's catalytic properties. Finally, the option of utilizing our novel ligands for the development of metal nanoparticle based sensors shall be evaluated.
