A series of open‐chain pentapyrroles and sapphyrins with highly electron‐withdrawing substituents (i.e., CN, CF3, or CO2Me) on the meso‐phenyl rings was synthesized and characterized as to the spectral properties, protonation reactions, and electrochemistry in non‐aqueous media. The investigated compounds are represented as (Ar)4PPyH3 and (Ar)4SapH3 where PPy and Sap correspond to the tri‐anion of...
