Characterization of cobalt phthalocyanine sheet polymer by gas chromatography mass spectrometry on its pyrolysis products

Cobalt phthalocyanine sheet polymer showed very high-thermal stability with a maximum polymer decomposition temperature of 500 °C in air, and 860 °C in nitrogen, with char yield of 85% at 800 °C in a nitrogen atmosphere. MS and GC-MS studies of the cobalt phthalocyanine sheet polymer were conducted at high temperatures ranging from 500 to 1000 °C. Tentative mechanisms are proposed for its modes of fragmentations and the most probable degradation products were identified by GC-MS.
