We report the synthesis of a set of 2Dmetal-organicframeworks (MOFs) constructed with organosilicon-based linkers. These oligosilyl MOFs feature linear Sin Me2n (C6 H4 CO2 H)2 ligands (lin-Sin , n=2, 4) connected by Cu paddlewheels. The stacking arrangement of the 2D sheets is dictated by van der Waals interactions and is tunable by solvent exchange, leading to reversible structural transformations
我们报告了用有机硅基连接基构建的一组二维金属有机框架(MOF)的合成。这些低聚甲硅烷基MOF具有通过铜桨轮连接的线性Sin Me2n(C6 H4 CO2 H)2配体(lin-Sin,n = 2,4)。2D薄片的堆叠排列由范德华相互作用决定,并且可以通过溶剂交换进行调节,从而导致许多晶相和非晶相之间可逆的结构转变。
