Spin-coated films of 1,4,8,11,15,18,22,25-octa-iso-pentyloxyphthalocyanine lead (PbPc(iso-PeO)8) complex were obtained and characterized by IR spectra, UV–vis absorption spectra. A good linear relationship of the absorbance and solution concentration was detected. Low concentration solution could afford smooth, homogeneous and porous macrostructure film surfaces as indicated by atomic force microscopy. The responses of the films to NO2, NH3, acetone and ethanol vapor were investigated at room temperature. In addition, the response and recovery characteristics, reversibility, selectivity and stability of the film to NO2 were also studied. The results indicated that the PbPc(iso-PeO)8 derivative could be exploited as an NO2 sensor at room temperature.
