Counterion‐Mediated Luminophore Dimerization
Angewandte Chemie, EarlyView.The choice of anion selectively directs the solution‐state aggregation of a cationic luminophore, dictating its photoluminescence. Some anions cause emission from a monomeric state, some induce excimer formation, and others lead to dimers, while the triflate counterion gives multichromatic emission from all three species.

Angewandte Chemie, EarlyView.Aziridination of alkenes is an important route to chiral nitrogen‐containing building blocks. We report that carbamate‐functionalized allylic alcohols undergo highly enantioselective aziridination using achiral dimeric Rh complexes ion‐paired with cinchona alkaloid‐derived chiral cations.
