This trend is opposite to that of n (optical-mode sensing), which exhibits high RH dependence at P/P0>0.6 (Figs3a and S5a) and thus represents the most sensitive (<2% RH) detection mode at high RH. The combination of these results strongly suggests that H2O adsorption on CuPcTs can be described in terms of two sequentially-occurring PFO reaction steps. The CuPcTs-H2O interaction can be tracked using a combination of gravimetric, optical, and electrical sensing modes, enabling accurate ( 2.5%) sensing in the ~0-95% RH range with a detection limit of less than 0.1% RH.

Spectrophotometric-chemometrics study of the effect of solvent composition and temperature on the spectral shape and shift of copper and nickel phthalocyanines in different aqueous-nonaqueous mixed solvents. PCA results indicate that significant changes in optical constants which occur near 6070% RH are a result of the emergence of a secondary process which becomes active after significant H2O adsorption has taken place in the film, which suggests that the secondary principal component is related to dielectric screening caused by H2O saturation of CuPcTs domains. The basic copper phthalocyanine has a very low solubility in water (0.009 mg/L) and in octanol (0.0004 mg/L). Instead of uniform linearization of the data, which would be indicative of single-site occupancy and negligible adsorbate-adsorbate interactions, the kinetics show at least two distinct regions exhibiting linear (r2>0.98) behavior: one region with slope 0.2 to 0.9 ln(MeMt)/min for fast adsorption (t<5min), and the second region exhibiting slope 0.020 to 0.25 ln(MeMt)/min for slower adsorption (t>15min).

Journal of membrane science The results suggest that rapid H2O adsorption takes place at hydrophilic sulfonyl/salt groups on domain surfaces at low RH, while slow adsorption and diffusion of H2O into CuPcTs crystallites leads to a mixed CuPcTs-H2O phase at RH > 60%, resulting in high frequency dielectric screening of the film by water and dissociation of Na+ from CuPc(SO3-)4 ions. This approach involves heating phthalonitrile with a copper salt, usually copper(I)chloride at 200C to 240C. 6, 045501045501 (2016).
