• A novel [36]octaphyrin analogue embedding two N‐confused pyrrole units demonstrated unique prototropy‐coupled isomerization between the Figure‐of‐eight and dumbbell conformers. Upon bis‐metal coordination, fixation of fully π‐conjugated Figure‐of‐eight structures was achieved as referred from the X‐ray crystal structure. Chirogenesis of the helical enantiomers was proved by intense circular dichroism (CD) response in the near infrared (NIR) region. Eight‐figured chirality: A novel [36]octaphyrin analogue embedding two N‐confused pyrrole units demonstrates unique prototropy‐coupled isomerization. Upon bis‐metal complexation, fully π‐conjugated, helical Figure‐of‐eight structures are realized. Distinct CD response in the NIR region confirms chirogenesis of the helical enantiomers.
