Organic semiconductive materials are known to considerably modify their electrophysical properties on adsorption of the active gases at low temperatures. The conductivity, resistance-temperature relationship, sensor properties relative to nitric oxide, oxygen and hydrogen sulfide of films based on oligo- and polyphthalocyanines containing Co, Cu, Fe and Mn were investigated in the present work. Polymeric films were deposited on the test structures with a pair of interdigital metal electrodes formed at their surface. The investigations were carried out under the sensor thermal stabilization conditions in the range 50 - 250 °C with the constant values of the heater resistance.
