Iron-phthalocyanine complexes immobilized in nanostructured metal oxide as optical sensors of <font>NO</font>_{<font>x</font>} and <font>CO</font>: NMR and photophysical studies

This paper presents the research that is currently undergoing in our group toward the development of optical sensing layers based on iron(II) phthalocyanine complexes immobilized on nanostructured solid supports. Several FePc - N donor ligands have been prepared and coated into different nanostructured metal oxides. Optical properties, chemical variables, analytical features, selectivity rates, response times and type of nanostructure supports have been evaluated; in some cases, interesting correlations between them have been deduced. In addition, thermostability studies have been carried out, providing access to a second generation of nanostructured metal oxides.
