Lines show exponential fits. 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 9, 970984 (2012). 2012 Jan;32(1):157-61. The Temkin model is particularly well-suited for predicting gas phase equilibrium with surfaces that contain a distribution of binding energies and explicitly accounts for adsorbate-adsorbate interactions by acknowledging that the heat of adsorption decreases linearly with adsorbate coverage27, 28. By Elsevier Science pp-115 (2003). The description is analogous to that for copper porphyrins, which are also formally derived by double deprotonation of porphyrins. Sauerbrey, G.

These findings suggest the potential of the examined ZnPc-BODIPY pentad to be efficient photosynthetic antenna in the Peak positions of the B- and Q-bands shift to lower energies and the probability of * transitions decrease by 50% as RH increases from 3% to 90%. Dyes and pigments ISSN 2045-2322 (online). At RH>60%, the value of C1 begins decreasing. Federal government websites often end in .gov or .mil. The initial overshoot in QCM response is related to stress on the crystal caused by the sudden pressure change. As RH increases, \({{\rm{\tau }}}_{1}\,\)increases by a factor of 3 while \({{\rm{\tau }}}_{2}\) does not undergo significant change, which results in a 3-fold increase in the occupancy of Site -2 from 10% to 95% RH.

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. [12] Using such methods, approximately 57,000tonnes (63,000Imperial tons) of various phthalocyanines were produced in 1985. The authors declare that they have no competing interests. )4 ions are left with 4 charges. Directed electron transfer in Langmuir-Schfer layers of porphyrin-fullerene and phthalocyanine-fullerene dyads in inverted organic solar cells. Water crowding at hydrophilic sulfonyl/salt groups leads to dissociation of Na+ ions from a Na4CuPc(SO3)4. Results from double exponential and PFO kinetic models suggest that at least 2 distinct sites are active during H2O adsorption on CuPcTs. There are many derivatives of the parent phthalocyanine, where either carbon atoms of the macrocycle are exchanged for nitrogen atoms or the peripheral hydrogen atoms are substituted by functional groups like halogens, hydroxyl, amine, alkyl, aryl, thiol, alkoxy and nitrosyl groups. )4 Here, sensitivity refers to the smallest RH changes detectable by the particular measurement technique at a given water vapor pressure P/P0 as estimated from the signal to noise ratio (SNR) for each response. & Riegler, H. Solubility properties of unsubstituted metal phthalocyanines in different types of solvents. Since the electron transfer from the singlet ZnPc to It is paramagnetic with one unpaired electron per molecule. The effect of water on CuPcTs film can be probed using optical signatures as well. The value of R/R0 exhibits roughly exponential behavior, reaching equilibrium at ~50% RH, which suggests that water adsorption alters DC conductivity of the film only before water saturation of CuPcTs domain surfaces has occurred. 9, 1588015886 (2017).
