N2 - We report a study of the effect of magnetic field on the structural organization and sensory properties of thin titanyl phthalocyanine (TiOPc) layers deposited by vacuum thermal evaporation. It is shown that magnetic field (directed perpendicular to the substrate surface) does not affect the phase composition of the layers which are represented by II-triclinic and I-monoclinic crystal modifications in both cases. The crystallites of both phases demonstrate preferential orientations, the angles between molecular planes and the substrate are 62.53° and 5.30°, respectively. The 2D GIXD study shows that magnetic field significantly improves the crystallinity of obtained thin layers; the conductivity increases by ~10 times, but the sensory response to ammonia does not change. Irradiating the layer obtained in magnetic field by fast neutrons (fluence 3·1014 cm–2) decreases the conductivity by two orders of magnitude. This effect is not observed in the parallel experiment without magnetic field.
