Abstract
The pyrolysis of iron phthalocyanine (Fe-Pc) was studied in Ar gas up to 1000°C. The pyrolysis pattern of Fe-Pc was analogous to that of Co-Pc, but Fe-Pc was less thermo-stable than Co-Pc. On DTA, Fe-Pc showed endo-thermic reactions at 615, 645 and 690°C, and exothermic reaction at 770°C. In these, the endo-thermic reaction at 690°C was a new appearance that was not observed on Cu-Pc, Co-Pc or Ni-Pc, but the cause of this endo-thermic reaction was not clear. It seems that the iron in Fe-Pc promotes the growth of carbon structures of pyrolyzed Fe-Pc.
