Synthesis of Core‐Crosslinked Nanoparticles with Controlled Cylindrical Shape and Narrowly‐Dispersed Size via Core‐Shell Brush Block Copolymer Templates

Core‐crosslinked nanocylinders with well‐defined shape and narrowly‐dispersed size are prepared by using S 2 Cl 2 to react with the alkenyl functionalities of the PNb‐ g ‐PIp‐based core domain of cylindrical core‐shell brush block copolymer, PNb‐ g ‐PIp‐ b ‐PtBA (see figure). This strategy potentially may be further extended by using brush copolymer templates having different compositional, structural and topological features for the synthesis of a broad variety of crosslinked nanostructures with diverse shapes and sizes.
