Abstract

Gold particles with diameters in the nanometer range, stabilized by the presence of alkanethiols bound to the particle surface have been synthesized. A portion of these alkanethiols contained a terminal hydroxyl group, which was shown to be capable of coordinating titanium(1V). The resultant titanium(IV) alkoxide species was able to catalyze the polymerization of hexyl isocyanate under very mild conditions. The final product of the synthesis was a gold nanoparticle with poly(hexyl isocyanate) covalently bound to the surface. Proton NMR was used to confirm the formation of poly(hexyl isocyanate). Dynamic light scattering experiments showed that the hydrodynamic radii of the particles increased markedly after the polymerization reaction, verifying that the polymer formed was bound to the particles.
