Synthesis of Amphiphilic Star Polymer Catalyst for Photo-oxidation Reaction. |
| 초록 |
Methacrylate based amphiphilic star block copolymers with Pd-porphyrin cores were synthesized by Atom Transfer Radical Polymerization (ATRP). For this, a photosensitive porphyrin was modified as a multifunctional initiator and then a palladium was introduced into the porphyrin center. MMA (methyl metacrylate) was first polymerized from the Pd-porphyrin multifunctional initiator by Ru-based ATRP system to give PMMA star polymer and then PEGMA (poly(ethylene glycol) methyl ether methacrylate) was added to synthesize PMMA-PPEGMA star block copolymer with narrow polydsipersities. These amphiphlic star block copolymers with Pd-porphyrin cores were then examined as polymeric photo-catalysts in water (or methanol), where hydrophobic substrates were concentrated into the hydrophobic inner block segments and then reacted with singlet oxygen (1O2) generated by the Pd-porphyrin core under UV/visible light irradiation. |
