stabilize CUS due to their robust structure. Generally, the generation of CUS in MOFs needs prior activation under heat and high vacuum to remove labile molecules occupying the catalytic sites. Herein, we report a solvothermal synthesis of a ready-to-use copper MOF containing accessible pre-existing CUS that does not need activation.

配位不饱和位点 ( CUS ) 在金属中心催化中至关重要。金属有机框架 (MOF)因其坚固的结构为生成和稳定CUS提供了独特的机会。通常,MOFs 中CUS的产生需要在热和高真空下预先活化,以去除占据催化位点的不稳定分子。在此,我们报告了一种即用型铜 MOF 的溶剂热合成方法,该铜 MOF 包含不需要激活的可访问的预先存在的CUS 。单晶 X 射线衍射结构显示方形平面 Cu(II) 中心具有两个N-甲基咪唑 (Mim) 和一个苯二甲酸 (BDC),分子式单元为 [Cu II (BDC)(Mim)2 ] n ( Cu-1D ) 形成沿c轴的无限一维 (1D) 链。1D 链通过非共价 π–π、CH···π 和 H 键相互作用稳定,形成固态的 2D(片状)和 3D 网络。通过 Hirshfeld 表面分析研究了非共价相互作用的量化,并通过 SEM 分析证实了固态更高结构的形成。报道的Cu-1D MOF
