controlled assembly of goldnanoparticles in terms of the spatial arrangement and number of particles is essential for many future applications like electronic devices, sensors and labeling. Here an approach is presented to build up oligomers of mono functionalized goldnanoparticles by the use of 1,3‐bipolar azide alkyne cycloaddition click chemistry. The goldnanoparticles of 1.3 nm diameter are

The assembly of dumbbell structures as organic-inorganic hybrid materials is presented. Goldnanoparticles (NPs) with a mean diameter of 1.3 nm were synthesized in very good yields using a stabilizingdendrimer based on benzylic thioether subunits. The extended dendritic ligand covers the NP surface and contains a peripheral protected acetylene, providing coated and monofunctionalized NPs. These NPs

Ligand‐stabilizedgoldnanoparticles (Au NPs) are promising materials for nanotechnology with applications in electronics, catalysis, and sensors. These applications depend on the ability to synthesize stable and monodisperse NPs. Herein, the design and synthesis of two series of dendritic thioether ligands and their ability to stabilize Au NPs is presented. The dendrimers have 1,3,5‐trisubstituted
