Spectral Analysis of Tetraphenylporphyrins Synthesized Using Solar Irradiation

Abstract

Several tetraphenylporphyrins have been synthesized using solar irradiation focused by a parabolic reflector as the thermal heat source. The porphyrins were analyzed by UV-Vis, MS, 1H NMR, and 13C NMR to confirm that the desired porphyrin was synthesized. The spectra were also used to compare the porphyrins to those synthesized by conventional electrical heating methods. MS and NMR spectra will be discussed.
