Investigation of zinc bis(1,4-didecylbenzo)-bis(2,3-pyrido)porphyrazine as an efficient photosensitizer by cyclic voltammetry

摘要

The phthalocyanine analogue containing non-peripheral,long alkyl-substituted benzenoid rings and pyridine rings,zinc bis(1,4-didecyl-benzo)-bis(2,3-pyrido)porphyrazine was synthesized.The synthesized product is an interesting compound because quaternization of the pyridine nitrogen is expected to impart cationic amphiphilic character.Zinc bis(1,4-didecylbenzo)-bis(2,3-pyrido)porphyrazine was reacted with dimethyl sulfate and monochloroacetic acid to produce the quaternized products and with diethyl sulfate to produce the sulfo-substituted product;all such compounds displayed amphiphilic character.Identical peaks in cyclic voltammograms were obtained for the products before and after quaternization.Zinc bis(1,4-didecylbenzo)-bis(2,3-pyrido)porphyrazine had no changes in its reduction or oxidation properties compared to phthalocyanine analogues.
