Anion binding is important for sensing and/or removal of toxic or polluting compounds. Squaramides (shown in the red box) are a commonly used group for molecular recognition. They can recognise anions through hydrogen bonding to their amide protons. While squaramides have been used extensively in organic receptors including macrocycles, they have not been widely incorporated into discrete metallosupramolecular assemblies. Metallosupramolecular assemblies consist of organic ligands combined with metal ions, and these structures often have cavities capable of binding guests. This project will involve the synthesis of two simple ligands containing a squaramide, and the formation of their [MnL2n]2n+ cages (M = PdII and PtII, n = 2 or 3). The ability of these architectures to recognise relevant anions will then be explored.
