Abstract A novel polycationic [60]fullerene hexakis‐adduct has been synthesized and investigated by electrospray ionization and tandem mass spectrometry. The polycationic ligand system comprises 12 pre‐formed positive charges, compensated in the neutral molecule by bromide anions. Stable quasi‐molecular cations were obtained through the release of the anionic counter ions covering a charge‐state envelope from 3+ to 12+. Collision‐induced dissociation experiments revealed three fragmentation pathways. A dominant neutral loss channel leads to daughter ions of the same charge state as the highly charged precursor ion and singly charged daughter ions can be expelled from the polycations through two distinct dissociation channels involving both the neutral and the charge‐carrying part of their ligands.
