In analogy to the isophlorines discussed by Woodward , N,N ′‐dihydroporphycenes should be regarded as [4n]annulenes, which explains their extremely facile oxidation to the aromatic porphycenes. Compound 1 is the first example of an N,N ′‐dihydroporphycene to be synthesized. The phane‐like, colorless 1 and the deep violet, planar 2 constitute a redox system.
