PAMAM dendrimers can also be used as templating agents and nanoparticle stabilizers for the synthesis of bimetallic particles. The unique ability of dendrimers to host various metal precursors enables the simultaneous complexation of multiple metallic species at its various internal functional groups. The three primary methods of bimetallic nanoparticle synthesis through dendrimer stabilization are partial displacement, co-complexation, and sequential complexation.

It is worthwhile to point out that dendrimers can also be used as normal capping agents during the synthesis of nanoparticles that do not reside inside the cavities of dendrimers [59,60]. These dendrimer-stabilized nanoparticles, capped with several dendrimer molecules, are usually much bigger than DENs and will not be discussed in this book chapter. 

Abstract The divergent synthesis, properties and functions of dendrimers terminated by metallocenyl redox groups are briefly illustrated in this micro-review, with emphasis on molecular electronics, sensing with regenerable derivatized Pt electrodes and efficient catalysis with dendrimer-stabilized Pd nanoparticles.

Mesomorphic dendrimers containing electroactive units have potential for construction of dendrimer based molecular switches. Deschenaux et al. reported [154] the synthesis and liquid-crystalline properties of a novel dendrimer containing six mesomorphic ferrocene units. Apart from exhibiting a broad enantiotropic smectic A phase as determined by polarized optical microscopy, DSC, and XRD studies, thermogravimetry revealed the excellent thermal stability of the macromolecule. 

The use of dendrimers constitutes an attractive stabilization mode for the synthesis of metal nanoparticles for several reasons ...
