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 complex through intermolecular ··· 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 for dissolved iodine and 1.81 g g for iodine vapor. Furthermore, the iodine adsorbed within the channels can be readily released upon immersing the bound solid in CHCl, which allows the recycling of the adsorbent. This work develops a new porous molecular material promising for practical iodine adsorption.
获取能够有效捕获放射性碘的吸附剂对于核废料处理很重要;然而,开发具有高且可还原碘捕获能力的多孔材料仍然是一个挑战。在此,我们报告了一种通过分子间···相互作用构建的杯状 Pd 配合物的多孔自组装。该自组装具有沿所有三个笛卡尔坐标的通道的立方结构,使其能够有效地捕获碘,溶解碘的吸附容量为 0.60 gg,碘蒸气的吸附容量为 1.81 gg。此外,将结合的固体浸入 CHCl 中时,通道内吸附的碘可以很容易地释放出来,从而可以回收吸附剂。这项工作开发了一种新的多孔分子材料,有望用于实际的碘吸附。
