Triggered formation of thixotropic hydrogels by balancing competitive supramolecular synthons [PDF]
Soft Matter, 2013 Two component hydrogels have been obtained by formation of 1:1 complexes of bis(pyridyl urea)s with a range of dicarboxylic acids. The gels are thixotropic and undergo an assembly process in which short segments can reversibly assemble into an interconnected fibrous network.

Tautomerism‐Coupled Self‐Assembly and Transformations of Iminopyrrole Metallacages
Chemistry – A European Journal, Volume 31, Issue 63, November 12, 2025.Four metallacages with varying size, symmetry, and nuclearity were formed via the self‐assembly of 2,5‐diformylpyrrole, tren, and zinc(II) acetate. Tautomerization of the key diiminopyrrole motif to iminoaminoazafulvene altered the assemblies’ properties.

Crystal structure of 2-(4-chlorobenzamido)benzoic acid
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title molecule, C14H10ClNO3, the amide C=O bond is anti to the o-carboxy substituent in the adjacent benzene ring, a conformation that facilitates the formation of an intramolecular amide-N—H...O(carbonyl) hydrogen bond that closes an S(6) loop ...

Hydrogen-bonding synthons in lamotrigine salts: 3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazin-2-ium 2-[(2-carboxyphenyl)disulfanyl]benzoate in its monohydrate and anhydrous forms [PDF]
, 2016 Lamotrigine is a drug used in the treatment of epilepsy and related convulsive diseases. The drug in its free form is rather inadequate for pharmacological use due to poor absorption by the patient, which limits its bioavailability.
