Bioinspired catalysis and bromoperoxidase like activity of a multistimuli-responsive supramolecular metallogel: supramolecular assembly triggered by pi–pi stacking and hydrogen bonding interactions

Abstract

We report the synthesis and characterization of a new self-assembled VO₂-L metallogel. Gel formation was investigated by dissolving VO₂-L in various solvents and it was found that water/methanol (1 : 9 (v/v) ratio) induces gel formation. The single crystal X-ray structure of the VO₂-L metallogel exhibits C–H⋯O and N–H⋯O hydrogen bonding interactions and pi–pi stacking. The VO₂-L xerogel obtained after removing the solvents was found to exhibit outstanding performance in catalysis. Bromoperoxidase-like activity of the VO₂-L metallogel was also reported. The present catalytic studies are simple and proceed under mild conditions.
