摘要：

Spin-coated layers of ZnTPP have been used as optochemically interacting materials to detect 4-aminophenol, following the UV-vis optical absorption variations obtained by the exposure of the sensing layers to vapour analyte diluted in dry-air controlled atmosphere. A multichannel monitoring of the variation in the sensing layer main optical absorption bands after interaction with 4-aminophenol allow us to study the interaction mechanism between analyte and metalloporphyrin. Morphological characterization of the sensing layer was also performed by atomic force microscopy. (c) 2005 Elsevier B.V. All rights reserved.
