We report the synthesis of a set of 2D metal-organic frameworks (MOFs) constructed with organosilicon-based linkers. These oligosilyl MOFs feature linear Si Me (C H CO H) ligands (lin-Si , 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 between many crystalline and amorphous phases.
我们报道了一组由有机硅基连接体构建的二维金属有机框架(MOF)的合成。这些低聚硅基MOF具有由铜桨轮连接的线性SiMe(C6H4CO2H)配体(lin-Si,n = 2, 4)。二维片层的堆积排列由范德华相互作用决定,并且可通过溶剂交换进行调节,从而导致在许多晶相和非晶相之间发生可逆的结构转变。
