Sažetak
With the recent emphasis on the importance of porous materials, so called porous hydrogen bonded organic frameworks (HOFs) have started gaining attention. A well-known class of HOFs are bisguanidinium organodisulfonates (GS), extensively explored due to their diverse host- guest chemistry and inclination towards architectural isomerism. Especially interesting is the persistence of the 2D hydrogen bonded sheet motif, allowing the targeted synthesis of a multitude of different pillared architectures (such as the bilayer or brick structure) where the type of architecture depends on the size of the guest and the pillar type. Most importantly, these materials have been shown to exchange guest molecules in a single crystal-to-single crystal fashion. Surprisingly, despite the stability of these frameworks, the desolvation of GS has not been extensively studied, and the structures of their empty forms - either 'collapsed' or 'open/porous' - have gone unreported. As a result, the formal existence of microporosity in the GS class of compounds has not yet been established. In this work we study the desolvation of guanidinium 1, 4-benzenedisulfonate materials and their absorption of gases via Single Crystal-to- Single Crystal transformations, demonstrating their formal microporosity.
