91, 92 Dendrons and Dendrimers with different degrees of branching, often represented by the so-called generations, or G, can be made by multistep synthesis. They can also be obtained from commercial sources nowadays. 5 for polyamidoamine (PAMAM) dendrimers. In typical synthesis, first, metal ions are trapped within the dendritic cores. 5. Synthetic strategy for making metallic nanoparticles stabilized in PAMAM dendrimers for catalysis. First, metal ions are complexed with the tertiary amine groups of PAMAM.

Schematic representation of the synthesis of metallic nanoparticles in solution for catalysis. 80 (Adapted with permission from Ref. 80 A stabilizer is necessary because naked nanoparticles are thermodynamically and kinetically unstable and tend to aggregate into bulk metal that is inactive in catalysis. The stabilizers typically come in the form of organic ligands,81 dendrimers,82, 83 or polymers,84 and contain donor atoms that are capable of binding palladium. Organic Ligand- and Polymer-Stabilized Pd-NPs for the Heck Reaction.

For instance, phenylene-bridged PMO containing diphenylphosphine ligands was prepared via supramolecular self-assembly of bissilylated bridging phenylene precursors with triblock co-polymers as templates. After removal of the polymer templates, diphenylphosphine-containing PMO was obtained. 126 The presence of Pd(II) within the mesoporous catalysts was determined by inductively coupled plasma optical emission spectrometer. The inclusion of organic moieties and other surface parameters of the material was determined by solid-state nuclear magnetic resonance spectroscopy, nitrogen gas adsorption, X-ray diffraction (XRD), and TEM.
