摘要：

Some new kinds of metal porphyrin derivatives were designed and synthesized. LB multilayer films of metal porphyrin derivatives were deposited on a specially designed FET, The interaction between the device and ambient gases such as NO2, NH3, CO and H2S was studied at appropriate heating powers. The results show that only cobalt porphyrin was sensitive to NO2, and the length of aliphatic chain effects the sensitivity, responsivity and stability.
