Resumen:
Ionic liquid and buffer mixture media are first reported in the peroxidase-catalyzed polymerization of phenol. Yield of 100% with molecular weights of 7000 KDa, as assessed by size-exclusion chromatography (SEC), were attained using 1-butyl-3-methylimidazolium tetrafluoroborate-buffer mixtures with added hydrogen peroxide. The simplicity of the process and the low vapor pressure of the solvent media allow an eco-friendly alternative to the general synthesis of polyphenolic-type biopolymers. Evidence for the consequent polyphenol (PPO) was obtained from solid-state (13)C cross-polarization magic angle spinning (CP-MAS) NMR spectroscopy and FT-IR.
