9,10-Quinoxaline-fused porphycenes <b>1a-H₂</b> and <b>1b-H₂</b> were synthesized by intramolecular McMurry coupling. As a result of the annulation of the quinoxaline moiety on the porphycene skeleton, <b>1a-H₂</b> and <b>1b-H₂</b> display absorption and fluorescence in the near infra-red (NIR) region. Additionally, the quinoxaline moieties of <b>1a-H₂</b> and <b>1b-H₂</b> act as electron-withdrawing groups, introducing lower reduction potentials than for pristine porphycene. The protonation occ ...[more]
