Orthogonal Quintuple‐Stimuli Responsiveness in an Ultrastable, Ultrabright Cu16 Nanocluster via Molecular and Supramolecular Engineering

open access: yesAdvanced Optical Materials, Volume 14, Issue 9, 6 March 2026.
Through simultaneous molecular and supramolecular engineering, an atomically precise nanocluster Cu16 with ambient ultrastability and ultrabright luminescence is constructed. Cu16 employs a dual structural/luminescent channel mechanism to achieve orthogonal responsiveness to five external stimuli, demonstrating multidimensional signalling capability ...

A ROBUST EIGHT–MEMBERED RING MOTIF IN THE HYDROGEN-BONDED STRUCTURE OF -(PHENYLAMINO)PYRIDINIUM- DI(METHANESULFONYL)AMIDATE

open access: yesIndonesian Journal of Chemistry, 2002
The compound was prepared by dissolving 2-(phenylamino)pyridine (0.52 g ; 3.0 mmol) and di(methanesulfonyl)amine (0.51 g; 3.0 mmol) in 5 mL methanol. Slow partial evaporation of the solvent at low tempertaure (-30 oC) gave a yield of 0.66 g (64%) and ...

Triggered formation of thixotropic hydrogels by balancing competitive supramolecular synthons [PDF]

open access: yesSoft 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.
