Sensing Properties of Palladium and Lanthanide Porphynates Embedded in Nanoporous Silica Gel-Materials

Solid gel-films and volume gel-matrices on the basis of silica materials doped with palladium porphyrinate, lutetium and gadolinium tetraphenylporphyrinates were prepared.Spectral-luminescent, sensing properties to molecular oxygen and effect of the gas environment were studied.Nanoporous silicate gel-materials doped by palladium porphynate demonstrate relatively high sensitivity to oxygen and can be considered as perspective optical sensors for oxygen.
