Conductivity and gas species content of (AlPcF)n thin films exposed to O2 or NO2

Abstract (AlPcF) n thin films were exposed to O 2 or NO 2 diluted in N 2 . Variations of electrical conductivity and of O 2 or NO 2 species mass in the film were simultaneously recorded at room temperature all along exposures to these gases. Experimental results are explained by such phenomena as sorption of O 2 or NO 2 in the phthalocyanine film, exchange of sorbed species, and chemisorption (charge transfer).
