Our group has recently published a News and Views article in the Chinese Journal of Structural Chemistry, titled "CO2-Switched Porous Metal-Organic Framework Magnets" (Chin. J. Struct. Chem. 43 (2024) 100241).

This News and Views article reviews recent serial work published in Angewandte Chemie International Edition (Angew. Chem. Int. Ed. 62 (2023) e202312205) and the Journal of the American Chemical Society (J. Am. Chem. Soc. 145 (2023) 26179–26189). It also provides perspectives on further applications of CO2-switched porous magnets, highlighting their potential in real-world scenarios.

This article explores the innovative use of CO2 to regulate the magnetic properties of porous metal-organic frameworks (MOFs). By employing a donor-acceptor mechanism, our research demonstrates how electron transfer between the metal unit and the organic ligand can lead to significant changes in the magnetic phase. Notably, our findings reveal the ability to reversibly switch between paramagnetic and ferrimagnetic states, and to create antiferromagnetic ordering upon CO2 adsorption. These transformations have promising implications for developing highly sensitive gas sensors and novel data storage devices, aligning with environmental goals for CO2 management.
