Supramolecular Aggregates of Amino Acid‐Functionalized 1,8‐Naphthalimides for Chiral Recognition

Chemistry–Methods, Volume 6, Issue 7, July 2026.
We synthesized three self‐assembling, amino acid‐functionalized 1,8‐naphthalimides. We studied their aggregation in solution and demonstrated their chiral recognition ability by fluorescence and resonance light scattering measurements. Notably, these fluorescent probes maintain their chiral recognition ability when incorporated in solid supports like ...

A Hydrogen‐Bonded Organic Biradical in the Gas Phase

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
Hydrogen‐bonded dimers of the TEMPOL radical are investigated by vibrational spectroscopy in the gas phase and shown to occur in at least two conformations, a stretched one with a strong hydrogen bond to the radical centre and a bent one with more pronounced London dispersion interactions. ABSTRACT Persistent organic radicals from the TEMPO family such
