Anion recognition based on an isothiouronium-derived organization

Abstract

Isothiouronium groups have great potential for use as an anion-binding unit in supramolecular chemistry, due to a high NH acidity for action as an ionic hydrogen bonding donor. Also the synthetic susceptibility allows us to fabricate self-organized systems of anion recognition. Here, we report isothiouronium-derived long-chain amphiphile 1 and isothiouronium-modified Au nanoparticles 2. The intrigued aspects in line with organized approach for anion recognition in aqueous media are discussed.
