A Semiconducting Supramolecular Co(II)-metallohydrogel: An Efficient Catalyst for Single-pot Aryl-S Bond Formation at Room Temperature
A novel mechanically stable supramolecular Co(II)-metallohydrogel has been synthesized. Cobalt(II) nitrate hexahydrate and monoethanolamine as a low molecular weight organic gelator are used to get the gel. The mechanical stability of the supramolecular hydrogel was analyzed. The morphology of the supramolecular metallohydrogel was scrutinized. The semiconducting feature of the metallohydrogel was studied. The conducting property of Co(II)-metallohydrogel establishes the Schottky barrier diode type nature. The catalytic role of the Co(II)-matallohydrogel based room temperature single pot Aryl-S coupling reaction have also been explored. Most interestingly, the Co(II)-metallohydrogel based catalytic Aryl-S coupling reaction does not need to perform any column-chromatographic purification protocol to get the pure Aryl-thioethers. Thus, through this work the semiconducting Schottky barrier diode application and the catalytic role for the room temperature single pot Aryl-S coupling reaction of a supramolecular Co(II)-metallohydrogel has been explored.
