Porous organic cages have emerged over the last 10 years as a subclass of functional microporous materials. However, among all of the organic cages reported, large multicomponent organic cages with 20 components or more are still rare. Here, we present an [8 + 12] porous organic imine cage, CC20, which has an apparent surface area up to 1752 m2 g–1, depending on the crystallization and activation conditions. The cage is solvatomorphic and displays distinct geometrical cage structures, caused by crystal-packing effects, in its crystal structures. This indicates that larger cages can display a certain range of shape flexibility in the solid state, while remaining shape persistent and porous.

大型,形状灵活,拟形态多孔有机笼的合成。

在过去的十年中,多孔有机笼已经成为功能性微孔材料的一个子类。但是,在所有已报道的有机笼子中,具有20个或更多成分的大型多组分有机笼子仍然很少见。在这里,我们介绍了一个[8 + 12]多孔有机亚胺笼CC20,视晶化和活化条件而,其表观表面积高达1752 m 2 g –1。该笼是溶剂化的,在其晶体结构中显示出由晶体堆积效应引起的独特的几何笼结构。这表明较大的笼子在固态时可以显示一定范围的形状柔韧性,同时保持形状的持久性和多孔性。
