Abstract

Unsymmetrical zinc bis (didecylbenzo) -3, 4-dipyridoporphyrazine having two nonperipheral didecyl-benzenoid rings and two pyridinoido rings was synthesized from a mixture of same amount of 3, 6-didecylphthalonitrile and 3, 4-dicyanopyridine in the presence of zinc chloride. Zinc bis (didecylbenzo) -3, 4-dipyridoporphyrazine was obtained as a mixtures of several position isomers, which was separated into four fractions and the components were characterised with 400 MHz proton nuclear magnetic resonance, visible and fluorescence spectroscopies, and cyclic voltammetry. The visible spectroscopy showed correlation between splitting of Q-band and molecular structure of each position isomer.
