We (1) investigate water adsorption kinetics on CuPcTs for better understanding the effects of relative humidity (RH) on hydrophilic phthalocyanines, and (2) assess CuPcTs as a humidity-sensing material. The effect of water on electrical conductivity is most pronounced at low RH, when water clustering around hydrophilic moieties hinders electronic charge carrier hopping between adjacent CuPcTs molecules. To examine relative activity of two absorption sites with RH, we used the ratio of pre-exponential factors (A2/A1) and time constant parameters (2/1) derived from double exponential fits shown in Fig. Exposure controlsAppropriate engineering controlsGeneral industrial hygiene practice.Personal protective equipmentEye/face protectionUse equipment for eye protection tested and approved under appropriategovernment standards such as NIOSH (US) or EN 166(EU).Skin protectionHandle with gloves.

Agranovich, V. M. Excitations in organic solids. CuPc sublimes at above 500C under inert gases (nitrogen, CO2). (, Humidity effect on electrical properties. At RH>60%, water saturation of CuPcTs domains leads to dielectric screening of the CuPcTs electronic charge carriers by dipolar water layers, which results in dramatic decreases in the values of n and k. Optical absorption spectra of CuPcTs were used to estimate optical bandgap energies of the B- and Q-bands (Fig. Phthalocyanine is formed through the cyclotetramerization of various phthalic acid derivatives including phthalonitrile, diiminoisoindole, phthalic anhydride, and phthalimides. 34, 735742 (2000).

We used 1/R as a measure of electrical conductivity, where R is the DC resistance. Shaded regions represent uncertainty range. Integration of an M-phthalocyanine layer into solution-processed organic photovoltaic cells for improved spectral coverage. Higher yields may be achieved with the solvent process (> 95%) than with the baking process (70 to 80%), so that the solvent process has initially simulated more interest. At low RH, the films dielectric response to H2O adsorption is weak, since delocalization of -electrons in the phthalocyanine ring allows high electronic polarizability and dielectric constant37. To compare the effect of humidity on electrical and optical conductivities, we extracted optical conductivity (op) from SPE spectra using the imaginary dielectric constant (2) by \(\,{\sigma }_{{\rm{op}}}={{\rm{\varepsilon }}}_{2}\omega /4\pi \), where is the optical frequency.

Journal of The Electrochemical Society 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).
