Disentangling structure-dependent antioxidant mechanisms in phenolic polymers by multiparametric EPR analysis

Abstract

Excellent and selective correlations between the electron-transfer (ET) or hydrogen atom transfer (HAT) capacity (DPPH and lipid peroxidation inhibition assays) and EPR indices of π-electron spin delocalization delineate specific structural determinants of antioxidant activity in biomimetic phenolic polymers.
