Superhelicenes in the Gas Phase: Experimental and Computational Evidence of Stable Radical Cation Dimers
Chem. comm., 59, 5882-5885
Date: Apr 25, 2023

Electrospray-ionization mass spectrometry (ESI-MS) readily produces stable radical cation π-dimers of the superhelicenes. Energy-resolved collision experiments reveal the dissociation of the dicationic dimer into two singly charged superhelicenes. DFT calculations indicate that open-shell dications composed of two radical cations are thermochemically more attractive than the closed-shell dimer formed by a doubly charged and a neutral superhelicene.
