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.
