Diblock copolymers spontaneously assemble into nanostructures such as spheres, cylinders, and lamellae, of which the size and morphology can be regulated by the molecular weight and volume fraction of copolymers. We synthesized polystyrene-b-poly(pentafluorophenyl methacrylate) (PS-b-PFMA) diblock copolymers and α-pentafluorophenylester poly(methyl methacrylate) (α-PFP-PMMA) homopolymers by the reversible addition fragmentation chain transfer (RAFT) polymerization. Since the reactive ester group in these polymers can easily react with alkyl amines to form amide bonds, quantum dots and organic dyes can be attached to these polymers. Quantum dots as well as dye-functionalized polymers can be arranged in nanostructures of diblock copolymers so that we can control the fluorescence resonance energy transfer (FRET) between quantum dots and dyes. Nanostructures of functional diblock copolymers were visualized by transmission electron microscopy. |
