A 2D coordination polymer prepared with bulky diethylformamide solvates exhibits channels which allow dipyridyl bridging ligands to diffuse into the crystal lattice. The absorbed dipyridyls thread through the pores of one layer and substitute the surface diethylformamide molecules on the neighboring layers to stitch alternate layers to form flexible interpenetrated metal–orgaic frameworks. The threading process also results in exchange of the bulky diethylformamide solvates for aqua to minimize congestion and, more strikingly, forces the slippage of two‐dimensional layers, while still maintaining crystallinity.

将2D聚合物层缝入单晶内的柔性互穿的金属有机框架中

用大体积的二乙基甲酰胺溶剂化物制备的2D配位聚合物具有允许二吡啶基桥接配体扩散到晶格中的通道。被吸收的二吡啶基分子穿过一层孔，并替换相邻层上的表面二乙基甲酰胺分子，以缝合交替的层，从而形成柔性的互穿金属有机骨架。穿线过程还导致将笨重的二乙基甲酰胺溶剂交换为水基，以最大程度地减少拥塞，更令人震惊的是，迫使二维层打滑，同时仍保持结晶度。
