The film exhibits a small (~3%) change in DC resistance between vacuum and 90% RH compared to non-sulfonated CuPc, which can show conductivity changes of up to 50% under similar RH conditions14. Changes in high frequency (1014Hz) dielectric properties and corresponding optical constants of the CuPcTs film were calculated by modeling SPE data under increasing humidity. Muckley, E.

Insoluble in general solvents in Zhejiang Province. 2005;246:327333. N.L. [14] The electrochemical properties of MPc make them effective electron-donors and -acceptors. CuPc can be easily processed into a thin film for use in device fabrication, which makes it an attractive qubit candidate.[31]. Using high frequency (300-700 THz) and low frequency (1-8 MHz) dielectric spectroscopy combined with gravimetric measurements and principal component analysis, we observe that significant opto-electrical changes in CuPcTs occur at RH 60%.

[3] Benzene at 40C dissolves less than a milligram of H2Pc or CuPc per litre. Before Changes in the slopes of n and k with RH (FigureS5a) indicate the presence of a 2-step process. The combination of these results strongly suggests that H2O adsorption on CuPcTs can be described in terms of two sequentially-occurring PFO reaction steps. Insights into the modeling of adsorption isotherm systems. The rapid thickness change at RH>70% is consistent with formation of a mixed H2O-CuPcTs phase facilitated by hydrogen bonding between H2O adsorbates and gas-phase water molecules16, 17, 38. Figure2b shows \({k}_{1-1}\) (left axis) and \({k}_{1-2}\) (right axis) plotted as a function of vapor pressure.

Areas of interest are the oxygen reduction reaction and the sweetening of gas streams by removal of hydrogen sulfide. 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. )4 ions15, 16 which contribute to charge transport in CuPcTs at RH>45%12. There has since been significant research on H2Pc and MPc resulting in a wide range of applications in areas including photovoltaics, photodynamic therapy, nanoparticle construction, and catalysis.

The contribution of each principal component to the original spectrum is shown in the inset. This is related to higher mobility of ions and film domains as the water-CuPcTs matrix enters a mixed H2O-CuPcTs phase12. (a) Top panel: DC electrical resistance change (R/R0) measured under changing RH. CAS Bookshelf During the first step, H2O molecules undergo rapid adsorption at hydrophilic sulfonyl/salt groups near CuPcTs domain surfaces. Claessens, C. G., Hahn, U. 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. The excitation transfer from the singlet BODIPY to eboun, J., Hamek, A., Dugan, T. & Kroupa, M. In Electronic System-Integration Technology Conference (ESTC), 2010 3rd.

Single-site H2O adsorption is modelled by the rate equation \(\,d{M}_{ad}/dt=\,{k}_{2}^{^{\prime} }[{{\rm{H}}}_{2}{{\rm{O}}}_{vap}][{M}_{e}-{M}_{t}]\), where \(d{M}_{ad}/dt\) is the rate of mass adsorption, \({k}_{2}^{^{\prime} }\) is the second order rate constant, \([{{\rm{H}}}_{2}{{\rm{O}}}_{vap}]\) is the concentration of H2O vapor, and \([{M}_{e}-{M}_{t}]\) is the concentration of active adsorption sites (\({M}_{e}\) is the mass adsorbed at equilibrium at a given P/P0 and \({M}_{t}\) is the mass adsorbed at time t at a given P/P0). Fit lines correspond to colors used in the bar graph. (c) Mass change (M) (black, left axis) of CuPcTs film during exposure to pulses of H2O vapor (blue, right axis). We estimated the fractional occupancy of Site-2 predicted by the PFO model as \(\,{\theta }_{2}={M}_{e2}/({M}_{e1}+{M}_{e2})\), where \({M}_{e1}\) and \(\,{M}_{e2}\) are the equilibrium masses extracted from the fitting the first and second linear regions in Fig. Combining gravimetric and optical techniques, we demonstrate the possibility of humidity sensing in the 095% RH range with 2.5% resolution.

Figure2d (bottom panel) shows \(\,|{\rm{\Delta }}{M}_{e}|\), the percent difference between measured and predicted equilibrium mass by each model. [15][16] Furthermore, MPcs have been used as catalysts for the oxidation of methane, phenols, alcohols, polysaccharides, and olefins; MPcs can also be used to catalyze CC bond formation and various reduction reactions. Water exposure leads to significant decreases in k between 550 and 650nm and decreases in n between 450 and 900nm. Box 2008, Oak Ridge, TN, 37831-6496, USA, Eric S. Muckley,Christopher B.

Hu, H., Trejo, M., Nicho, M., Saniger, J. Thin Solid Films In general, a crude copper phthalocyanine is produced by reacting phthalic anhydride, urea, copper/copper salt and ammonium molybdate (catalyst) in high-boiling solvent such as o-nitrotoluene, trichlorobenzene or alkyl benzenes. At 10% RH, 97.5% of H2O molecules adsorb rapidly at Site-1 (\({{\rm{\tau }}}_{1}\)<2minutes) while 2.5% adsorb at Site-2 over the course of an hour (\({{\rm{\tau }}}_{2}\,\) 50minutes). 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. RH levels inside the flow cell were controlled using an L&C Science RH-200 humidity generator and measured with an additional humidity probe at the outlet of the flow cell.
