Cover Feature: Sulfur‐Bridged Cationic and Neutral [6]Helicenes: Chiral Trityls With Property and Stability Twists (ChemistryEurope 11/2026)
The Cover Feature depicts sulfur-bridged [6]helicenes at the boundary between neutral and cationic states. Starting from azathia helicene 10, protonation, heteroatom exchange with ammonium, and sulfur oxidation provide access to structurally related dyes with markedly different electronic and photophysical properties. The shoreline symbolizes this tunable chemical landscape and the transitions between molecular states. More information can be found in the Research Article by G. Pescitelli, J. Lacour and co-workers (DOI: 10.1002/ceur.70368).
