Gold nanocomposites with rigid fully conjugated heteroditopic ligands shell as nanobuilding blocks for coordination chemistry.

Monodisperse and solvent adaptable gold nanoparticles stabilized by rigid and fully conjugated modified neocuproinium and terpyridinium salts have been characterized and further used as nanobuilding blocks for the synthesis of gold nanoparticles functionalized by polypyridyl ruthenium complexes.
