摘要：

Spin-coating films of copper, lead and nickel 1,8,15,22-tetra-iso-pentyloxyphthalocyanine (Cu, Pb and NiPc(iso-PeO)(4)) were obtained and characterized by absorption spectra and atomic force microscopy. The gas sensing behaviors of the films were investigated with respect to NH3 at room temperature. In addition, the effects of film morphology and center metal on gas sensing properties were also discussed. It was found that the MPc(iso-PeO)(4) films exhibited good response, reversibility, stability and faster response and recovery characteristic to NH3. The responses were in the following order: CuPc(iso-PeO)(4), PbPc(isoPeO)(4) and NiPc(iso-PeO)(4), and the response and recovery were in the following order: Cupc(iso-PeO)(4). NiPc(iso-PeO)(4) and PbPc(iso-PeO)(4). (C) 2011 Elsevier B.V. All rights reserved.
