2-(Benzenesulfonamido)pyridinium perchlorate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the title compound, C11H11N2O2S+·ClO4−, the dihedral angle between the benzene and pyridinium rings is 87.33 (10)°. An intramolecular N—H...O interaction, with an S=O-bonded O atom as receptor, occurs in the cation. In the crystal structure, ion pairs occur, being linked by strong N—H...O hydrogen bonds. The perchlorate anion plays a further role in

Supramolecular Polymerization and Morphological Transformation of Dynamic Helical Poly(Phenylacetylene)s via Chain‐End Host–Guest Interactions

Angewandte Chemie, EarlyView.
A helical polymer whose chain ends are connected through pillar[5]arene‐based host–guest interactions translates molecular helicity into supramolecular morphology. Solvent‐triggered helicity inversion accompanied by changes in chain rigidity switches the supramolecular architecture between cyclic and rigid‐rod nanostructures.

2-(Benzenesulfonamido)pyridinium nitrate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the title compound, C11H11N2O2S+·NO3−, the dihedral angle between the benzene and pyridinium rings is 87.59 (8)°. An intramolecular C—H...O interaction occurs in the cation. In the crystal structure, ion pairs occur, being linked by two strong N—H...O interactions, formingR22(8) loops. The packing is further stabilized by weak C—H...O interactions.

Molecular and Cellular Hallmarks of Age‐Related Vestibular Hair Cell Degeneration

Advanced Science, EarlyView.
This study utilizes single‐cell RNA‐seq transcriptomes, advanced imaging, and electrophysiology to examine universal and cell‐type‐specific aging signatures of vestibular hair cells. The study shows that impaired hair bundle function is a key driver of age‐related vestibular dysfunction.

Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

Angewandte Chemie, EarlyView.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...
