Abstract
The present work describes the preparation and characterization of a new cobalt(III) porphyrin coordination compound named (chlorido)(nicotinoylchloride)[
-tetra(
-chlorophenyl)porphyrinato]cobalt(III) dichloromethane monosolvate with the formula [Co
(TClPP)Cl(NTC)]·CH
Cl
(
). The single-crystal X-ray molecular structure of
shows very important ruffling and waving distortions of the porphyrin macrocycle. The Soret and Q absorption bands of
are very red-shifted as a consequence of the very distorted porphyrin core. This coordination compound was also studied by fluorescence and cyclic voltammetry. The efficiency of our four porphyrinic compounds-the H
TClPP (
) free-base porphyrin, the [Co
(TClPP)] (
) and [Co
(TClPP)Cl] (
) starting materials, and the new Co(III) metalloporphyrin [Co
(TClPP)Cl(NTC)]·CH
Cl
(
)-as catalysts in the photochemical degradation was tested on malachite green (MG) dye. The current voltage of complexes
and
was also studied. Electrical parameters, including the saturation current density (J
) and barrier height (ϕ
), were measured.
