Tetrakis-4-(2,4-di-tert-amylphenoxy)phthalocyaninato-polysiloxane was synthesized. Its molecular structure was confirmed by elemental analysis, IR and UV-vis spectra. The gas-sensitive properties of its Langmuir-Blodgett films exposed to NH3, I2 and NO2 in air were measured. The results showed that the detection sensitivity on exposure to NH31 in air can reach 0.1 ppm, while it can reach 100 ppm on exposure to NO2 and I2 in air.
