چکیده

A novel highly sensitive optical NO2-selective sensor was developed using phthalocyaninato-iron(II) as a selective complexing agent. In order to solubilize the ironII+phthalocyanine and to obtain the monomer species, a N-donor ligand was used as a solvent. The membrane solution was deposited onto a novel aluminum oxide/hydroxide nanoporous material by a spin-coating technique. The chemical reaction principle and the preparation of this new sensor are presented in detail. The effect of the type and concentration of the N-donor ligand, and the influence of the iron phthalocyanine concentration were investigated as well as the effect of the composition and the morphological c c a i a 1 ©
