✦ Synopsis

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 NH ~3~, I ~2~ and NO ~2~ in air were measured. The results showed that the detection sensitivity on exposure to NH~3~ in air can reach 0.1 ppm, while it can reach 100 ppm on exposure to NO ~2~ and I ~2~ in air.

Until now, with a few exceptions, Reflectance Anisotropy Spectroscopy (RAS) has been applied mostly to inorganic semiconductors and metals, proving to be a powerful tool to investigate their optical properties, via anisotropies introduced by the surface in otherwise isotropic bulk materials. Recentl
