Construction of large multi-component coordination cages becomes much more challenging as the number of building blocks increases. A giant hexameric calix[4]resorcinarene-based coordination cage (cage-1) was successfully designed through the precise tuning of ancillary rigid tetracarboxylic acid. Significantly, cage-1 exhibited reversible uptake of volatile iodine, suggesting that it could serve as a porous material for efficient capture and separation of radioactive iodine.
随着构建模块数量的增加,构建大型多组分配位笼变得更具挑战性。通过对辅助刚性四羧酸进行精确调控,成功设计出一种基于杯[4]间苯二酚的巨型六聚体配位笼(笼-1)。值得注意的是,笼-1对挥发性碘具有可逆吸收作用,这表明它可作为一种多孔材料用于高效捕获和分离放射性碘。
