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. Reaction models show that H2O undergoes 2-site adsorption which can be represented by a pair of sequentially-occurring pseudo-first order reactions. Phthalocyanine (H 2 Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C 8 H 4 N 2) 4 H 2 and is of theoretical or specialized interest in chemical dyes and photoelectricity.. )4 ions are left with 4 charges. Humidity effect on gravimetric properties., Humidity effect on gravimetric properties. (d) Top panel: comparison of Site-2 occupancy (\({\theta }_{2}\)) as estimated from pseudo-first order kinetic and double exponential models. The basic copper phthalocyanine has a very low solubility in water (0.009 mg/L) and in octanol (0.0004 mg/L). (. It does not represent any guarantee of the properties of the product.

Combining gravimetric and optical techniques, we demonstrate the possibility of humidity sensing in the 095% RH range with 2.5% resolution. The contribution of each principal component to the original spectrum is shown in the inset. [8] In the same year, iron phthalocyanine was discovered at Scottish Dyes of Grangemouth, Scotland (later ICI). : 147-14-8EC-No. 1907/2006 (REACH). Cu 2+ Pc 2. 2022. Two copper phthalocyanines are shown in the figure below. Scientific Reports (Sci Rep) CuPc belongs to the D4h point group. [32] Copper phthalocyanine dyes are produced by introducing solubilizing groups, such as one or more sulfonic acid functions. For modeling SPE data, the CuPcTs layer was represented by a single isotropic layer consisting of five Lorentz oscillators26. 1c) and showed no significant dependence on water vapor pressure, desorption kinetics were not analyzed in terms of PFO and PSO models. DOI: 10.1021/acs.inorgchem.2c03425. 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. b8$B "/2y0b?C%-9#Q\X2iDaRh5rEZ@eZJ. In crystals with unit cells composed of n molecules, the nondegenerate excited states of each molecule are comprised of n bands, resulting in several absorption peaks22.

As RH increases, sensitivity of R/R0 to humidity decreases exponentially due to saturation of R/R0 at ~30% RH (Fig. The results strongly suggest that adsorption/desorption of water can be described by a double active site model that includes one strongly hydrophilic site which becomes quickly saturated as RH increases (Site-1) and one site which becomes more active as Site-1 is filled (Site-2)31. Copper was first discovered by Early Man prior to 9000 BC. 74160,[13][14][15] and British Rail Blue. Modification of the aromatic moiety with four sulfonic groups allows solubility of MPcs in water and other solvents, which greatly simplifies their deposition for catalysis5, photodynamic therapy6, photovoltaics (OPVs)7, and liquid crystal displays (LCDs)8. Muckley ES, Naguib M, Wang HW, Vlcek L, Osti NC, Sacci RL, Sang X, Unocic RR, Xie Y, Tyagi M, Mamontov E, Page KL, Kent PRC, Nanda J, Ivanov IN. doi: 10.1016/j.apsusc.2004.11.036. Careers. Agranovich, V. M. Excitations in organic solids. At the initial discovery of Pc, its uses were primarily limited to dyes and pigments. They remarked on the enormous stability of these complexes but did not further characterize them. 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. The choice of the solvent is very important, as it plays a significant role in the generation of impurities. Clipboard, Search History, and several other advanced features are temporarily unavailable. Copper (II) 1,2,3,4,8,9,10,11,15,16,17,18,22,23,24,25-hexadecafluoro-29H,31H-phthalocyanine (F16CuPc) is an organic molecule that can be used as an electron transporting material with good air-stability and an electron mobility of 0.11 cm2/Vs . The PCA results support proposed adsorption kinetics models, which indicate that a secondary adsorption process occurs after H2O saturation of strongly hydrophilic sites. Enhanced photocurrent and stability of organic solar cells using solution-based TS-CuPc interfacial layer. You can change or update your cookiesettingsat any time. Red lines indicate examples of double exponential fits. (b) Top panel: Optical film thickness as RH is increased (adsorption, black squares) and decreased (desorption, red circles). 141, 140144 (2008). As calculated from SPE measurements, the optical film thickness was roughly 50nm when measured at ambient RH. 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. CuPc has often been investigated in the context of molecular electronics. 74160. DOT (US)Not dangerous goodsIMDGNot dangerous goodsIATANot dangerous goods. %PDF-1.4 % Insights into the modeling of adsorption isotherm systems. 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. [17] No specific dangers have been associated with this compound. CAS International journal of environmental research and public health 3d). Shipping documentation includes a Certificate of Analysis and Safety Data Sheet (SDS). The phase has a larger overlap and thus, a smaller Cu-Cu spacing (~3.8) compared to the phase (~4.8). 127, 15061517 (1980). Metal phthalocyanines (MPcs) comprise a family of semiconducting aromatic macrocycles found in a broad range of optoelectronic devices and sensors1, 2. Article Despite the hydrophilic character of sulfonyl/salt complexes, the response of sulfonated MPcs like CuPcTs under changing relative humidity (RH) conditions has not been thoroughly studied11, 12. )Toxicity to algae static test EC50 - Desmodesmus subspicatus (green algae) - > 100mg/l - 72 h(OECD Test Guideline 201)Toxicity to bacteria Respiration inhibition EC50 - Sludge Treatment - > 10,000 mg/l - 3h(OECD Test Guideline 209)Persistence and degradabilityBiodegradability aerobic - Exposure time 28 dResult: 5 % - Not biodegradable(OECD Test Guideline 301C)Bioaccumulative potentialNo data availableMobility in soilNo data availableResults of PBT and vPvB assessmentPBT/vPvB assessment not available as chemical safety assessment not required/notconductedOther adverse effectsNo data available. Please Check that the Lot Number you have entered is correct. It is a transparent staining color and can be applied using glazing techniques. 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). 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. Google Scholar. Integration of an M-phthalocyanine layer into solution-processed organic photovoltaic cells for improved spectral coverage. RH dependence of principal components is shown in main plots with each components contribution to the actual spectra shown in the insets. (a) AFM image of CuPcTs film. 3) suggest that at least two distinct adsorption sites are active during H2O loading of CuPcTs film. Sauerbrey, G.

Preparation of porous titania film and its application in solar cells. You can easily unsubscribe at any time. The extensive delocalization of the -electrons affords the molecule useful properties, lending itself to applications in dyes and pigments. The information in this document is based on the present state of our knowledge and is applicable to the product with regard to appropriate safety precautions. Probing Molecular-Scale Catalytic Interactions between Oxygen and Cobalt Phthalocyanine Using Tip-Enhanced Raman Spectroscopy. [19][20][21] Phthalocyanine is also used on some recordable DVDs. Due to its stability, phthalo blue is also used in inks, coatings, and many plastics. The VOC is significantly larger than that produced by similar cells based on the commonly studied copper phthalocyanine (CuPc)/C60 heterojunction (VOC = 0.46 V).
