Abstract

© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Gold nanoparticles (Au NPs) with tailor-made structures and properties are highly desirable for applications in catalysis and sensing. In this context, surface modifications of Au NPs are of particular relevance. Herein, we present a sequential surface modification of Au NPs with AgI coordination complexes, which can be converted into Ag0-doped Au NPs by simple ligand-exchange reaction. The key innovative element of this surface modification is a multifunctional bioxazoline-based ligand that brings coordinated AgI into close proximity to the particle surface.
