Outline of Final Research Achievements |
Here, we describe the structural specific redox-activity of synthetic amphiphilc block copolymers (PEG-b-Pys), which consist of hydrophilic poly(ethylene glycol) (PEG) and hydrophobic poly(4-pyridyl propyl acrylate) (Py). Of particular interests is that the redox-activity of copolymer is clearly induced in only block-type polymer conformation. The result of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) cation radical scavenging assay was strongly suggested the generation of electron spices from PEG-b-Pys. There was high correlation with the redox-activity of PEG-b-Pys and auto-reducing behavior of metal ions.
