CdSe/CdSConjugated Polymer Core–Shell Hybrid Nanoparticles by a Grafting-From Approach

Hybrid particles consisting of II–VI semiconductor quantum dots and conjugated polymers are increasingly relevant, but access is limited by the usual step-growth nature of polymer formation. We report on a grafting-from approach by controlled Pd­(II)-mediated polymerization to yield CdSe/CdS nanocrystals with a defined number of polyfluorene chains grown from their surface, as concluded from MALDI-TOF analysis and quantitative end-capping. Further studies underline the importance of matching the monomers’ and the surface-bound initiators’ reactivity
