A Dynamic Porous Magnet Exhibiting Reversible Guest‐Induced Magnetic Behavior Modulation

Abstract

A flexible 3D porous magnet [KCo7(OH)3(ip)6(H2O)4]·12 H2O based on unprecedented trigonal-prismatic heptanuclear CoII clusters (see figure) is reported to undergo a reversible single-crystal-to-single-crystal transformation on the desorption/adsorption of guest molecules, accompanied by reversible magnetic property changes. This might be applied for the sensing of coordinative, paramagnetic, small molecules such as O2 and NO.
