Fabrication and catalytic activity of polymeric boronate ester-supported gold nanoparticles

Abstract

Polymeric boronate esterification of benzene-1,4-diboronic acid with 1,2,4,5-tetrahydroxybenzene and pentaerythritol led to submicron particles composed of poly(dioxaborole)s. Gold nanoparticles deposited on the submicron particles were fabricated by solid grinding and deposition reduction methods, which exhibited a selective reduction of nitro group of 4-nitrostyrene.
