Abstract

Two different generations of poly(propylene imine) dendrimers (GnPPI, n = 2, 3) terminated by 15-membered nitrogen-containing triolefinic macrocycle (15-MAC) on the periphery (Gn-M) were synthesized. The structure and composition of Gn-M were characterized by FT-IR, 1H NMR, and elemental analysis. The Rh metallic dendrimer-stabilized nanoparticles (Rh DSNs) were prepared by utilizing Gn-M as stabilizers and analyzed by UV-vis spectroscopy. Transmission electron microscopy (TEM) was adopted to characterize the size and particle morphology of Rh DSNs. The G3-(Rh) DSNs demonstrated higher catalytic activity than G2-(Rh) DSNs for the hydrogenation of nitrile-butadiene rubber (NBR).
