Hexameric Palladium(II) Terpyridyl Metallomacrocycles: Assembly with 4,4′-Bipyridine and Characterization by TWIM Mass Spectrometry

TWIM peaks: A macrocycle containing 12 PdII terpyridyl centers was assembled using 4,4′‐bipyridyl ligands and characterized by NMR and traveling wave ion mobility mass spectrometry (TWIM‐MS). The macrocyclic architecture was also examined by tandem mass spectrometry and collisionally activated disso...

Zusammenfassung:TWIM peaks: A macrocycle containing 12 PdII terpyridyl centers was assembled using 4,4′‐bipyridyl ligands and characterized by NMR and traveling wave ion mobility mass spectrometry (TWIM‐MS). The macrocyclic architecture was also examined by tandem mass spectrometry and collisionally activated dissociation (CAD) experiments (see picture; C gray, N blue, Pd orange), and the resulting fragments were monitored by time‐of‐flight mass analysis.
