Similar behavior is observed in the RH dependence of k (FigureS5b). [17] The abbreviation "CuPc" is also used.[18]. The results demonstrate that when CuTCPc is used as a donor material, the performance of the device ITO/CuTCPc/PCBM/Al shows an open circuit voltage (V(OC)) of 0.54 V, a short circuit current (J(SC)) of 0.825 mA/cm2, a fill factor (FF) of 32.3% and the power conversion efficiency (nu) of 0.14%.

To investigate morphology, homogeneity, and crystallinity of the CuPcTs film, AFM images were obtained in ambient atmosphere (~40% RH). 115, 2492024930 (2011). The Journal of Physical Chemistry B 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. A soluble derivative of copper phthalocyanine, that is 2,9,16,23-tetra carboxyl copper phthalocyanine (CuTCPc), is synthesized in this paper. [4] Substituted phthalocyanine complexes often have much higher solubility. 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%.

Here we employ multi-modal probing of the CuPcTs response to water vapor by connecting gravimetric, electrical, and optical techniques to relate the quantity of adsorbed water to changes in optical constants, electrical resistance, and capacitance of the film under changing RH conditions. The applications of CuTCPc as donor and interlayer materials in solar cell devices are investigated. Disclaimer, National Library of Medicine Femtosecond laser [30] Epub 2017 Oct 17.

Bottom panel: Bandgap energy (Eg) of Q-band (left axis) and B-band (right axis). 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). The plot of \(\mathrm{ln}({M}_{e}-{M}_{t})\) vs. t is shown in Fig. A common component on the artist's palette, phthalo blue is a cool blue with a bias towards green. The r2 values of each fit are shown in the inset bar graph. 3b bottom panel) using a Tauc plot (FigureS6). We used 1/R as a measure of electrical conductivity, where R is the DC resistance. To obtain The fit to the equivalent circuit model is shown by the red line in FigureS9. 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. This site needs JavaScript to work properly. This approach involves heating phthalonitrile with a copper salt, usually copper(I)chloride at 200C to 240C. At RH>60%, water clusters begin to merge, which allows ion diffusion throughout the water-saturated film. HHS Vulnerability Disclosure, Help At RH>60%, the formation of H2O layers containing mobile Na+ ions can increase the effective contact area at electrodes and result in improved electronic transport by allowing charge carriers to hop between hydrated ionic structures consisting of coordinated Na+ and dipolar H2O, leading to a decrease in R2. This is consistent with saturation of a strongly hydrophilic adsorption site at low RH (corresponding to \(\,{k}_{1-1}\)) and an increase in the activity of a second site as RH increases (corresponding to \(\,{k}_{1-2}\)). Temkin and double exponential models achieve r2>0.998 and best represent the measured H2O adsorption isotherm. ChemElectroChem 2008;8:7597. The adsorption of water onto previously adsorbed H2O clusters or multilayers in the mixed H2O-CuPcTs phase at RH>60% does not further affect carrier mobility.

(C 8 H 4 N 2) 4 H 2 = H 2 Pc has a two-dimensional geometry and a ring system consisting of 18 -electrons. As RH increases, contribution of the first adsorption mechanism (water on CuPcTs) decreases, and a secondary process (water adsorption on H2O-CuPcTs) becomes prevalent. and K.V. Of all pure metals, only silver has a higher electrical conductivity. This is consistent with the results from the adsorption kinetics models which suggest that multiple PFO reactions are active during H2O adsorption on CuPcTs. The absorption spectrum of ZnPc-BODIPY pentad covers most of the visible region ADS Aqueous solubility of copper phthalocyanine-3,4',4,4'-tetrasulfonic acid tetrasodium salt (CuPcTs) enables fabrication of flexible electronic devices by low cost inkjet printing.

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. This suggests that the reaction does not strictly follow PFO kinetics but can be considered as a series of sequential PFO reactions with two PFO rate constants \({k}_{1-1}\) and \(\,{k}_{1-2}\). 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. 105, 1030810315 (2001).

Nanoscale. Sign up today! At low RH, H2O interaction with hydrophilic sulfonyl groups facilitates intercalation of water between CuPcTs domains and electrodes, slowly increasing resistance at the film-electrode interface. Nitrogen was discovered by Daniel Rutherford in 1772. [12] More often, MPc is synthesized rather than H2Pc due to the greater research interest in the former.
