Unexpected Self-Reactivity of a Pyridinium–Benzimidazolate Zwitterion Leading to a Novel Atropoisomeric Scaffold with Single-Component White Light Emission
We report the discovery of a hitherto unknown reactivity consisting of self-coupling of a benzimidazolato-pyridinium zwitterion (<b>1</b>) leading to compound <i>rac</i><b>-3</b> with an intriguing atropoisomeric structural scaffold. This novel compound <i>rac</i><b>-3</b> was structurally characterized and investigated by DFT and TD-DFT calculations. Compound <i>rac</i><b>-3</b> shows rare single-component white light dual emission properties, which may pave the way for new opportunities in organic chemistry for luminescent materials, biology, or catalysis.
