제목 Preparation of nano-sized gold particles stabilized  α,ω-heterobifunctional PEOs
초록 Functionalized polymers have been used for preparation of nano-sized transition metals or metal oxides. In this respect, we synthesized α,ω-heterotelechelic poly(ethylene oxide) via anionic mechanism. After complete polymerization of ethylene oxide using potassium azidopropanate in THF, purified propylene sulfide was delivered into the reactor under high vacuum. The resulting α-azido-ω-thiolated PEO was used to prepare the gold nano particles. Practically, to get azide-funtionalized gold nanoparticles, gold nanoparticles were prepared by using the PEO-based bifunctionalized polymer was employed bearing the chain-end thiolated group with HAuCl4 in water at 60°C, followed by reduction using NaBH4. In this presentation, the preliminary results will be discussed.
