Click-dendrimer-stabilized nanoparticles are a new family of dendrimer-stabilized nanoparticles that is particularly suitable for catalytic studies [59, 66],... 

The collection of different nanoparticles having different designed sizes is crucial to the study of the mechanisms in nanoparticle catalysis. These click dendrimer-stabiUzed nanoparticles are efficient catalysts for selective olefin hydrogenation under ambient conditions, and the turnover Ifequencies, turnover numbers and yields depend on the nanoparticle size. The smallest nanoparticles (from Gi) are the most active ones, in agreement with a classic hydrogenation mechanism entirely proceeding at the nanoparticle surface [66]. On the other hand, the turnover numbers, turnover frequencies and yields are independent on the type of nanoparticle stabilization and sizes of the nanoparticles for the Suzuki cross coupling reaction between chlorobenzene or bromobenzene and PhB(OH)2. Moreover, the...

One of the most important advances in synthesizing dendrimers is through the use of the cycloaddition reaction between azides and alkynes, which has become known as click... 

Figure 7.7 The synthesis of dendrimer molecules using click chemistry proceeds with high yield. Each step results in the cycloaddition reaction between azide-containing molecules and alkyne molecules to form triazole linkages.

Dendrimers Containing Ferrocene-Type Units at Their Periphery By exploiting efficient synthetic approaches (dendrimer growth strategy pioneered by Newkome18 and click chemistry), several dendrimers containing 27 (compound 1, Fig. 6.1), 54, 81, and 243 ferrocene units in their periphery have been... 

Unprotected glycol-dendrimers, peptido- and redox-dendrimers and dendro-nized polymer organogels can also be prepared by click chemistry [18 c].

Click chemistry has proved to be a versatile strategy and has undergone a spectacular development in the last few years, as a broad spectrum of applications has been found. Thus, for example, this concept has been applied to the preparation of polymers [137-140], dendrimers [141-144], glycoclus-ters [145] and pharmacophores [118]. The 1,2,3-triazole moiety was found to be a mimic of the amide moiety, characterized by an enhanced stability towards hydrolysis and oxidations [118].
