摘要：

In this work, thin films of octasubstituted zinc phthalocyanine derivative (ZnPcR(8)) with bulky substituents R=-CH(2)N(SO(2)C(6)H(5)-CH(3))CH(2)(CH(2))(8)CH(3) are investigated as active layers of optical sensors for the detection of pentachlorophenol. Using total internal reflection ellipsometry (TIRE) technique response characteristics of ZnPcR(8) films to pentachlorophenol was studied in the concentration range 0.5-50 mu g/l. It was demonstrated that the specific binding of pentachlorophenol molecules causes substantial shift of Delta(lambda) spectrum. The minimum registered concentration of pentachlorophenol was 0.8 mu g/l. The results are supported by performing attenuated total reflection Fourier transform infrared (ATR-FTIR) difference spectroscopy. (C) 2009 Elsevier B.V. All rights reserved.
