While numerous hydrogen-bonded organic frameworks (HOFs) have been reported, typically these cannot be prepared predictablyo ri namodular fashion. In this work, we report af amilyo fn ine diamondoid crystalline porous frameworksa ssembled via hydrogen bondingb etween polyamidinium and poly-carboxylate tectons. The frameworks are prepared at room temperature in either water or water/ alcoholm ixtures. Importantly,b oth the cationic and anionic components can be varied and additional functionality can be incorporated into the frameworks, which show good stability including to prolonged heating in DMSO or water.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

We report the liquid-phase ultrasonic exfoliation of two layered hydrogen-bonded frameworks into monolayer, micron-sized, and water-stable nanosheets (HONs) connected purely by hydrogen-bonding interactions.

A reproducible metallocyclic motif containing amino-acid functionalised aromatic diimides has been employed to demonstrate remarkable control over entanglement topologies. [2]-Catenane and pseudo-rotaxane units give rise to 1D → 2D polycatenation, the formation of which can be sterically prevented, and a unique 1D → 3D polyrotaxane.

This review details the use of O–H⋯anion interactions in synthetic receptors, anion transport, self-assembly and catalysis.
