Capture and sensing of emerging pollutants is one of the increasing environmental concerns due to the adverse ecological and human health effects. Here, we report the synthesis of a supramolecular metal-organic framework (SMOF) [CrCu₆(μ-H₂O)₆(μ₃-OH)₆(μ-adeninato-κN3₃:κN9)₆](SO₄)_1.5 which is able to capture anionic drugs and exhibits magnetic properties useful for sensing purposes. The features of the nucleobase decorated CrCu₆ building block allow the incorporation of up to 9 drug molecules (i.e., ibuprofen and naproxen in this work) per heptameric entity. In addition, we provide a simple way to quantify the incorporated number of drug molecules through a magnetic sustentation experiment in which the field required to keep the particles attached to the electromagnet pole is linearly related to the total mass of the anionic counterion. In this way, it also provides an easy way to determine the amount of entrapped drug molecules, making this SMOF a promising candidate for environmental remediation technologies.

由于不利的生态和人类健康影响，捕获和感测新兴污染物是日益关注的环境问题之一。这里，我们报告一个超分子金属-有机骨架（SMOF）的CrCu的合成₆（μ-H ₂ O）₆（μ ₃ -OH）₆（μ-adeninato-κ N3 ₃：κ N9）₆ ]（SO ₄）_1.5，其能够捕获阴离子药物并显示出用于感测目的的磁性。核碱基修饰的CrCu _6的特征每个七聚体最多可结合9个药物分子（即布洛芬和萘普生）。此外，我们提供了一种简单的方法，可通过磁保持实验来量化药物分子的掺入数量，在该实验中，保持颗粒附着在电磁极上所需的磁场与阴离子抗衡离子的总质量成线性关系。这样，它也提供了一种简单的方法来确定被困药物分子的数量，从而使该SMOF成为了环境修复技术的有希望的候选者。
