Annotation	Thin layers of nickel and copper tetrasulfonated phthalocyanines (NiPcTS and CuPcTS) were prepared byMatrix Assisted Pulsed Laser Evaporation method. The depositions were carried out with KrF excimer laser(energy density of laser radiation EL= 0.1–0.5 J cm−2) from dimethylsulfoxide matrix. For both materialsthe ablation threshold EL-thwas determined. The following properties of deposited layers were char-acterized: (a) chemical composition (FTIR spectra); (b) morphology (SEM and AFM portraits); and (c)impedance of gas sensors based on NiPcTS and CuPcTS layers in the presence of two analytes – hydrogenand ozone. The prepared sensors exhibit response to 1000 ppm of hydrogen and 100 ppb of ozone evenat laboratory temperature.
