The first demonstration "polymeric ligands" for the immobilisation of quantum dots (QDs) is presented. Specifically, thiol-containing polystyrene microspheres were synthesised and used to incorporate QDs via a swelling/doping strategy. The resultant composite materials were shown to be highly stable against QD leaching in both apolar and polar solvents and retained an identical QD emission profile to non-immobilised QDs. This straightforward approach also allows easy access to controllable and reproducible multiple-QDcontaining microspheres.
