Cyclic voltammetry of non-peripheral thioaryl substituted phthalocyanines
چکیده انگلیسی

Phthalocyanines have become of major interest as functional colorants for dye-sensitized photovoltaic cells. Syntheses of non-peripheral (1,4,8,11,15,18,22,25) thioaryl substituted phthalocyanines have been reported. These phthalocyanines exhibited a Q band in the near-infrared region.In order to develop next generation photovoltaic cells, we have synthesized 1,4,8,11,15,18,22,25-octakis(thioaryl)phthalocyanines and estimated their electron transfer ability using cyclic voltammetry. In the cyclic voltammograms, these compounds showed reduction and oxidation potentials, which are attributed to the presence of the sulfur atoms in the thioaryl substituents at the peripheral positions of phthalocyanine.The electron transfer mechanisms of the phthalocyanines having cobalt and zinc as their central metal atoms were attributed to reduction and oxidation of their central metal, while electron transfer in the other metal-free compounds resulted from the highest occupied molecular orbital to the lowest unoccupied molecular orbital electron transitions.
