Abstract:

Partially quaternized fifth-generation poly(amidoamine) dendrimer-encapsulated RuRh bimetallic nanoparticles(DENs) were prepared via co-complexation method. The formation of DENs, the particle size and distribution of RuRh bimetallic nanoparticles were investigated by UV-Vis absorption spectroscopy, laser scattering analysis, and TEM. The results of FTIR and NMR spectroanalyses show that a high efficiency of regioselective hydrosilation modification of poly(methylhydrosiloxane) is achieved with the RuRh bimetallic DENs catalysts.

Key words: Quaternized poly(amidoamine) dendrimer, RuRh bimetallic nanoparticle, Poly(methylhydrosiloxane), Regioselective catalyzed modification
