Abstract

Branching out: A simple two-component system comprised of a Pd precursor and oleylamine has shown that both the rate of nanoparticle nucleation and growth can be controlled by manipulating the local ligand environment, thus allowing the facile selection of either Pd nanodendrites or monodisperse Pd nanoparticles (see TEM images). This ligand-controlled approach connects fundamental principles of coordination chemistry to nanostructure design.
