Reversible addition fragmentation chain transfer (RAFT) polymerization from unprotected cadmium selenide nanoparticles

Nanoparticles functionalized with a trithiocarbonate ligand allow RAFT polymerization merization to be performed from their surface. Homopolymers, random copolymers, and block copolymers can be grown radially from trithiocarbonate-covered CdSe nanoparticles (see scheme). This technique gives excellent nanoparticle dispersion in a wide range of polymers, while maintaining the unique photo-physical properties of the nanoparticles.
