Mgh. Vicente et al., ELECTROCHEMICAL AND SPECTROSCOPIC PROPERTIES OF CU(II) BETA-NITRO MESO-TETRA(PENTAFLUOROPHENYL)PORPHYRINS, Tetrahedron letters, 37(2), 1996, pp. 261-262
Some electrochemical and spectroscopic properties of the copper(II) de
rivatives of beta-unsubstituted, beta-mono-, beta-di- and beta-tri-sub
stituted meso-tetra(pentafluorophenyl)porphyrins are presented. The re
d-shift observed on the bands of the optical spectra, and the value of
the first and second reduction potentials of these compounds depend o
n the number of nitro substituents on the porphyrin macrocycle.
