研究了铜酞菁(CuPc)和铝氟聚酞菁(AlPcF)薄膜在稀释氧化气体O2、NO2和Cl2浓度阶跃下的电导变化。这与我们最近提出的描述气体-酞菁相互作用的模型非常一致，从而得出了实验上经常观察到的定律：(电导率)α(气体浓度)S。计算了不同温度下这两种酞菁对O2和NO2的敏感度。
Thin films of copper phthalocyanine (CuPc) and poly(phthalocyanine of aluminium and fluor) (AlPcF)nwere exposed to concentration steps of the diluted oxidizing gases O2, NO2and Cl2, and their conductivity variations were recorded at the same time. These are in good agreement with the model we recently proposed to describe gas-phthalocyanine interactions, leading to the law: (conductivity)α(gas concentration)s, which is often experimentally observed. The sensitivitiessof the two phthalocyanines to O2and NO2are calculated at various temperatures.
