Investigation of optical and humidity-sensing properties of vanadyl phthalocyanine-derivative thin films. A combination of gravimetric and optical detection modes was selected to enable the highest resolution (2.5% RH) humidity sensing in the entire 095% RH range, with gravimetric detection as the most sensitive mode for RH <50% and optical detection as most sensitive for RH >50%. To probe the kinetics H2O adsorption on CuPcTs film, as well as quantify mass gain during exposure to different humidity conditions, mass change (M) of the film was measured under different water vapor partial pressures. 1d.

Water saturation of the sulfonyl groups leads to dissociation of Na+ ions from SO3 At the initial discovery of Pc, its uses were primarily limited to dyes and pigments. Unsubstituted phthalocyanines strongly absorb light between 600 and 700nm, thus these materials are blue or green. Use proper gloveremoval technique (without touching glove's outer surface) to avoid skin contactwith this product. The geometry optimization showed that the phthalocyanine moiety is completely symmetric and form, perfect square planar complex with zinc. The PFO rate equation then becomes \(\,d{M}_{ad}/dt=\,{k}_{1}[{M}_{e}-{M}_{t}]\). I.I. b8$B "/2y0b?C%-9#Q\X2iDaRh5rEZ@eZJ.
