Abstract
Directed assembly for nanopatterning on semiconductor surfaces is of interest as a cost-effective approach for lithography on silicon, which is complementary to photolithography. In this work, self-assembly of block copolymers is used to produce nanoscale hexagonal arrays of gold hemispheroids, which are then incorporated into an optically transparent, flexible PDMS stamp. These “plasmonic stamps” can then be used to drive hydrosilylation of alkenes and alkynes on hydride-terminated silicon surfaces upon illumination with low-intensity green light [which corresponds with the absorption of the localized surface plasmon resonance (LSPR) of the gold nanostructures]. The resulting hexagonal arrays of nanoscale alkyl or alkenyl patches mirror the spacing of gold nanoparticles in the parent plasmonic stamp. Close examination of the hydrosilylated patches reveals that they are not continuous across the 20–30 nm diameter patches but instead display an annular motif, which closely resembles the plasmonic electric ...
