Deprotonated meso-hydroxyporphyrin as a stable π-electronic anion: the building unit of an ion-pairing assembly†
Abstract
The NiII complex of 5-hydroxy-10,15,20-tris(pentafluorophenyl)-porphyrin was synthesized as the precursor of a negatively charged π-electronic system. Deprotonation, which was examined through UV/vis and 1H NMR spectra, provided an anionic species as the building unit of an ion-pairing assembly in combination with an aliphatic cation.
