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.

(Chemical Presented) A state of (con)fusion: The introduction of a confused pyrrole ring into a meso-aryl sapphyrin framework destabilizes the macrocycle and forces a fusion reaction to occur. Subsequent metalation with rhenium results in further mutation to form a domino-fused sapphyrin with a fused penta-ring system (see scheme).
