Free based 5,10,15,20 meso-tetraphenyl porphyrin (H2TPP) and copper phthalocyanine (CuPc) films have been produced by means of a recently developed plasma based technique named glow discharge induced sublimation (GDS). The two macrocycles have been also deposited, for the sake of comparison, by means of commonly used deposition techniques, i.e. H2TPP by spin coating (SPIN) and CuPc by vacuum evaporation (VE). The physical properties of the films have been characterized by means of Fourier transform infrared analysis (FT-IR), scanning electron microscopy (SEM) and nitrogen physisorption measurements. FT-IR spectra point out the high purity of the GDS samples while SEM images and physisorption measurements highlight the much higher surface roughness and porosity of GDS samples with respect to the VE and SPIN ones. Optical sensing measurements, performed in differently concentrated ethyl alcohol atmospheres, highlight that GDS samples yield much higher response intensities than SPIN and VE films, short response times and complete recovery.
