Highly Efficient Uptake of Cs⁺ by Robust Layered Metal-Organic Frameworks with a Distinctive Ion Exchange Mechanism.

ABSTRACT: ¹³⁷Cs with strong radioactivity and a long half-life is highly hazardous to human health and the environment. The efficient removal of ¹³⁷Cs from complex solutions is still challenging because of its high solubility and easy mobility and the influence of interfering ions. It is highly desirable to develop effective scavengers for radiocesium remediation. Here, the highly efficient uptake of Cs⁺ has been realized by two robust layered metal-organic frameworks (MOFs), namely [(CH₃)₂NH₂]In(L)₂·DMF·H₂O (DMF = N,N'-dimethylformamide, H₂L= H₂aip (5-aminoisophthalic acid) for 1 and H₂hip (5-hydroxyisophthalic acid) for 2). Remarkably, 1 and
