Synthesis, aggregation and responsivity of block copolymers containing organic arsenicals

Abstract

Block copolymers containing an organic arsenical (AsAm) have been synthesised by aqueous SET-LRP. The block copolymers are pH and thermoresponsive, forming nanoparticles in aqueous solution. Under reductive conditions the particles are stabilised through the formation of As–As bonds and stability can be tuned as a function of the AsAm monomer feed.
