Isolating the ring-redox states of boron sub-phthalocyanines

Abstract

Ring-reduced and ring-oxidized boron subphthalocyanine complexes have been isolated and structurally characterized. The doubly reduced species forms a trinuclear cluster with intramolecular B–N_meso bonds, while the mono-oxidized system shows minimal bond localization. UV-visible absorption spectra and accompanying TD-DFT calculations are indicative of the ring-oxidation state.
