title: Dipyrrolyphenol as a precursor of π-electronic anion that forms ion pairs with cations.
abstract: A nitro-substituted dipyrrolylphenol was synthesized as a precursor of a π-electronic anion, whose phenolate (phenoxide) moiety upon deprotonation was stabilized by the hydrogen-bond-donating pyrrole NH, thus forming solid-state ion pairs with various cationic species.
