Description
Summary:Presented herein is an example of the conversion of an aluminum oxo cluster (AlOC) to an aluminum oxo cluster organic cage (AlOCOC). We successfully synthesized the first example of an aluminum cluster-based organic cage-Al 12 tetrahedral cage via an Al 3 cluster. The use of 4-pyrazolecarboxylic acid plays an important role in the construction of the organic cage. Due to the presence of partially deprotonated ligands, the hydrogen-bonding interactions between the discrete tetrahedra generate porous supramolecular structures. Considering the high porosity and the abundant N-H sites, we further investigated the performance of the material towards iodine capture. Presented herein is an example of the assembly of a tetrahedral metal-organic cage compound from a trinuclear Al( iii ) cluster. Such a synthetic method can be applied to the construction of cluster-based porous materials.
