(a–d) The change in bond lengths between porphyrin oligomer radical cations and their neutral precursors Δr = rcation – rneutral. (e–h) Gas phase spin density isosurfaces at isovalue 0.001 a.u. Calculations performed at the LC-ωPBE/6-31G* level of theory, ω = 0.2 a0–1. The colors in the spin density plots do not relate to those in parts a–d.
