The intense bright red color of the diprotonated derivatives of rubyrin ( 1 ), the largest expanded porphyrin to be characterized so far, is the source of the compound's name. A diprotonated alkyl derivative of 1 was synthesized efficiently. The molecule is nearly planar in the crystal—not unexpected for a large porphyrin‐like aromatic macrocycle.
