Abstract

The phthalocyanine analogue containing non-peripheral, long alkyl-substituted benzenoid rings and pyridine rings, zinc bis(1,4-didecylbenzo)-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.
