Porphyrin and Phthalocyanine Chemistry

Metal-catalyzed coupling methodologies have been employed in the synthesis of the key building block 3'-formyl-2,2':5',2"-terthiophene. Wittig olefinations with this aldehyde have produced five novel beta-styryl-substituted terthiophene monomers. These materials have been fully characterized by NMR spectroscopy, microanalysis, mass spectrometry, and X-ray crystal structure analysis. The results from the UV/visible spectroscopy and cyclic voltammetric investigations are reported.
