Abstract
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.
