Nanoparticles functionalized with a trithiocarbonate ligand allow RAFT polymerization 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 photophysical properties of the nanoparticles.
