An aqua-bridged Mn metal-organic framework was prepared, and a dramatic structural transformation occurs upon solvent exchange-resolvation and desolvation-resolvation processes. The desolvated phase, formed by removing the aqua bridges, exhibits selective CO(2) uptake over N(2), H(2), and CH(4). Further, antiferromagnetic couplings are also found between Mn spins in the secondary building units.
一种水桥联的锰金属有机骨架被制备出来，并且在溶剂交换-再水合以及去溶剂-再水合过程中发生了显著的结构转变。去溶剂相通过去除水桥联而形成，对 CO(2)相对于 N(2)、H(2)和 CH(4)具有选择性的吸附。此外，在次级构筑单元中的 Mn 自旋之间也发现了反铁磁耦合。
