The spectral data were in agreement with the proposed structure. The copper complex exhibited a shift in the Soret band in comparison to the non-metallated porphyrin and the extinction coefficient for the Soret band was on the order of 105 cm−1M−1. Trends observed in the oxidation and reduction potentials were consistent with the nature of the porphyrin. That is, the electron donating group in 5,10,15,20-tetra(N-ethyl-3-carbazolyl) porphyrin enhances oxidation and inhibits reduction.
