Metal-organic frameworks (MOFs) based on edge-transitive 6-c acs nets are well-developed and can be synthesized from trinuclear metal clusters and ditopic ligands, i.e., MOF-235 and MIL-88. The rational design of noncatenated acs-MOFs by symmetry-matching between trigonal prismatic organic ligands and trinuclear clusters, however, remains a great challenge. Herein, we report a series of acs-MOFs (NU-1500) based on trivalent trinuclear metal (Fe, Cr, and Sc) clusters and a rigid trigonal prismatic ligand courtesy of reticular chemistry. The highly porous and hydrolytically stable NU-1500-Cr can be activated directly from water and displays an impressive water vapor uptake with small hysteresis.
基于边传递的 6-c acs 网的金属有机骨架（MOFs）已经得到了很好的发展，可以通过三核金属簇和双齿配体来合成，例如 MOF-235 和 MIL-88。然而，通过三核簇和三角棱柱有机配体之间的对称匹配来合理设计非链状 acs-MOFs 仍然是一个巨大的挑战。在此，我们通过网状化学报道了一系列基于三价三核金属（Fe、Cr 和 Sc）簇和刚性三角棱柱配体的 acs-MOFs（NU-1500）。高度多孔且水解稳定的 NU-1500-Cr 可以直接从水中激活，并显示出令人印象深刻的水蒸气吸收，滞后很小。
