Metalloporphyrins serve important roles in biology and as components in emerging technological assemblies for energy conversion. In this report, we describe the synthesis and characterization of a novel cobalt(II) 5,10,15,20-tetrakis
(3-fluorophenyl)porphyrin bearing a 4-vinylphenyl surface attachment group at a beta position on the macrocycle. Electrochemical measurements show the 3-fluorophenyl groups at the meso positions of the porphyrin perturb the reduction potentials of the complex to more positive values as compared to
non-fluorinated analogs, thus allowing access to reduced cobalt porphyrin species at significantly less negative applied bias potentials. The complex, cobalt(II) 5,10,15,20-tetrakis(3-fluorophenyl)-2-(4-vinylphenyl)porphyrin, is abbreviated in this article as Gov-1 in honor of Govindjee for his pioneering investigations in the role of fluorine as a promoter of novel
protein-substrate interactions and the inspirational role he continues to have in encouraging young investigators in the areas of natural and artificial photosynthesis., D. Khusnutdinova, M. Flores, A. M. Beiler, G. F. Moore., and Obsahuje bibliografické odkazy
