A Porous π-Stacked Self-Assembly of Cup-Shaped Palladium Complex for Iodine Capture.

ABSTRACT: Acquiring adsorbents capable of effective radioiodine capture is important for nuclear waste treatment; however, it remains a challenge to develop porous materials with high and reversible iodine capture. Herein, we report a porous self-assembly constructed by a cup-shaped Pd^II complex through intermolecular π···π interactions. This self-assembly features a cubic structure with channels along all three Cartesian coordinates, which enables it to efficiently capture iodine with an adsorption capacity of 0.60 g g^-1 for dissolved iodine and 1.81 g g^-1 for iodine vapor. Furthermore, the iodine adsorbed within the channels can be readily released upon immersing the bound solid in CH₂Cl₂, which allows the recycling of the adsorb
