A Porous π-Stacked Self-Assembly of Cup-Shaped Palladium Complex for Iodine Capture
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<sup>II</sup>...

| description | 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<sup>II</sup> complex through intermolecular <i>π</i>···<i>π</i> 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<sup>−1</sup> for dissolved iodine and 1.81 g g<sup>−1</sup> for iodine vapor. Furthermore, the iodine adsorbed within the channels can be readily released upon immersing the bound solid in CH<sub>2</sub>Cl<sub>2</sub>, which allows the recycling of the adsorbent. This work develops a new porous molecular material promising for practical iodine adsorption. |
