The interaction between gas mols. and the active surface of thin org. film can generate variation in the phys. properties of the layer. Here, spin coated layers of 4 metallophthalocyanines which were used as optochem. interactive materials are reported together with a discussion concerning the preliminary data obtained with optical absorbance measurements in UV-vis spectral range onto these optical sensitive sensors. Glass substrates coated with metallophthalocyanine show good sensitivity and selectivity depending both on the metal and the peripheral substituents. A certain sensitivity towards tert-butylamine, diethylamine, dibutylamine, 2-butanone and acetic acid was found.
