In this text, the Chlorinated metallic porphyrin (TPPMncl and TPPFecl) thin films were fabricated by Spin-coated technique onto quartz substrates. In order to search for the gas-sensing characterization of Chlorinated metallic porphyrin Spin-coated films, the changes of UV-Visible absorption spectrums of TPPMncl and TPPFecl Spin-coated films respectively exposed in vapor of Chloroform, pyridine, Ammonia, triethylamine and dimethylamine were analyzed. The experimental results show that, the spectral response of TPPMncl and TPPFecl on organic gas molecular is obviously found. And we know that chlorinated metallic porphyrin film formed the J-aggregates. Moreover, through two kinds of chlorinated metallic porphyrin integral area rate of histogram, it is easy to identify and distinguish between the four kinds of volatile organic compounds. It indicates that these Chlorinated metallic porphyrin have gasochromic characteristics while responding with organic gas. Therefore, these materials can be prepared into gas sensor array for detecting VOCS.
