Deprotonated meso-hydroxyporphyrin as a stable pi-electronic anion: the building unit of an ion-pairing assembly

摘要

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