Getting in shape : Meso‐pentafluorophenyl triply N‐confused hexaphyrins have been synthesized in the free‐base and oxidized forms and shown to have a triangular shape and efficient emission in the NIR region (see picture). The triangular shape is achieved by the presence of alternating confused and normal pyrrole rings. DFT calculations show that the triangular shape is more stable than a rectangular form.
