Thin films of meso-octaethylporphyrinogen were deposited on suitable surface by Langmuir-Blodgett technique to obtain optical sensors using Surface Plasmon Resonance (SPR) technique. In particular such coatings were tested in the mol. recognition of alc. vapors such as ethanol and methanol. This resulted in a reversible shift in the resonance depth and position of the SPR curves. Different sensitivity and rate of response for different alc. mols. were found.

Abstract
Thin films of meso-octaethylporphyrinogen were deposited on suitable surface by Langmuir-Blodgett technique to obtain optical sensors using Surface Plasmon Resonance (SPR) technique. In particular such coatings were tested in the mol. recognition of alc. vapors such as ethanol and methanol. This resulted in a reversible shift in the resonance depth and position of the SPR curves. Different sensitivity and rate of response for different alc. mols. were found.File in questo prodotto:
