Tapered Bottlebrush Polymers for Templating Gold and Silver Nanoparticles with Shape Asymmetry (II.A.1.a.i.(1))
Abstract
Polymers can template the formation of metal nanoparticles, but the resulting metal nanoparticles are typically limited to the thermodynamically favored symmetric shapes. We propose here to use bottlebrush polymers, prepared via a combination of ring-opening metathesis polymerization and reversible-deactivation radical polymerization strategies to template the formation of gold (Au) and silver (Ag) nanoparticles (NPs) far from their thermodynamic equilibrium. Au and Ag NPs are well known for their plasmonic properties, i.e., their ability to transform light, due to the interaction of light with electrons in the nanoparticles. As plasmonics are heavily influenced by NP size and shape, and Au and Ag nanoparticles of the shapes proposed here have never been reported, we aim here to address this gap in knowledge. The results may lead to new properties that cannot be afforded using current technologies.
