Polymeric composites with quantum dots (QDs) can be interesting materials to combine unique properties of quantum dots with various merits of polymers such as optical transparency and easy processability. Thus, such organicinorganic composites can be valuable for many applications in electronic, photonic, and bio devices. However, the most serious problem to fabricate polymeric composites with quantum dots is the difficulty of homogeneous dispersion of quantum dots in a polymeric matrix. The inherent incompatibility of quantum dots with polymers results in aggregation of QDs, loss of transparency, and quenching of the fluorescence of QDs in composites. In this presentation, functional diblock copolymers were designed to disperse quantum dots in thin films. To optimize the incorporation of quantum dots into copolymer matrices, thiol-terminated PMMA-PLMA diblock copolymers were synthesized by RAFT polymerization, which were effective to disperse QDs without aggregation. |
