A novel N‐confused porphyrin (NCP) analogue bearing an external aza‐dipyrrin‐like coordination site was synthesized by a Schiff‐base forming reaction of N‐confused oxoporphyrin and 2‐aminopyridine derivatives. The chimera molecule enhances the intrinsic NH tautomerism of NCP to enable four possible tautomeric structures, three of which were identified by metal coordination.
