Abstract

Amphiphilic polymers having different polymerizable functional groups were synthesised and investigated as coatings for semiconductor nanoparticles (Quantum Dots, QDs). QDs coated with hydrophobic ligands were successfully transferred into water using these polymers and the assemblies were co-polymerized with N-isopropylacrylamide (NIPAM) by a precipitation polymerization method. In the resulting hybrid microspheres, QDs were uniformly distributed within the PNIPAM matrix. The influence of different polymerizable groups and counter ions of the amphiphilic polymer on the copolymerization process were investigated.
