Porous organic crystals crosslinked by free-radical reactions

Abstract

Two hydrogen-bonded crosslinked organic frameworks (H_COFs) were synthesized via free radical reactions utilizing butadiene and isoprene as crosslinkers. These H_COFs exhibit high crystallinity, enabling detailed structural characterization via single-crystal X-ray diffraction analysis. Subsequently, one of the olefin-rich H_COFs was converted to a hydroxylated framework through hydroboration–oxidation while maintaining the high crystallinity.
