Abstract: Porous organic cages have emerged over the last 10 years as a subclass of functional microporous materials. However, among all of the organic cages published, 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 ef-fects, 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.
