摘要：

The thin films of copper 2,9,16,23-tetra-isopropoxy phthalocyanine and 2,9,16,23-tetra-paramethyl-phenoxy phthalocyanine were prepared by spin-coating technique. The surface morphology and spectroscopic property of the thin films were characterized by AFM (Atomic force microscope), UV-Vis and FTIR spectroscopy. The results show that good films can be obtained under certain spin speed. The surface morphology of the two phthalocyanine films is different due to different substituent. The gas-sensing properties of the multilayers to CH3OH and C2H5OH were measured at room temperature. The spin-coating thin films exhibited high sensitivity and rapid response- recovery characteristics to these gases. The sensitivity of the films to C2H5OH is higher than that to CH3OH. Under the same test gas concentration, phenoxyl phthalocyanine film is more sensitive than alkoxy phthalocyanine film. The response and recovery time of the thin films to 30 mu L.L-1 of C2H5OH vapor is within 30 s and 60 s, respectively.
