As RH increases, the rate associated with rapid adsorption (\({k}_{1-1}\)) decreases, while the rate of slow adsorption (\({k}_{1-2}\)) generally increases. Would you like email updates of new search results? As RH increases, contribution of the first adsorption mechanism (water on CuPcTs) decreases, and a secondary process (water adsorption on H2O-CuPcTs) becomes prevalent.

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 This website requires certain cookies to work and uses other cookies to help you have the best experience.

We studied the interaction of H2O vapor with film of CuPcTs using a multi-modal approach which links gravimetric, broadband dielectric spectroscopy, and DC electrical resistivity measurements. Red lines indicate examples of double exponential fits. 1 represents 2 distinct sequentially-occurring PFO reactions. Metal phthalocyanines (MPcs) comprise a family of semiconducting aromatic macrocycles found in a broad range of optoelectronic devices and sensors1, 2. To obtain The discovery of metal phthalocyanines can be traced to the observation of intensely colored byproducts from reactions of phthalic acid (benzene-1,2-dicarboxylic acid) or its derivatives with sources of nitrogen and metals. Prior to H2O adsorption measurements, films were placed under 103Torr (1.33103mbar) vacuum for 24hours. Ammonium removal from aqueous solutions by clinoptilolite: determination of isotherm and thermodynamic parameters and comparison of kinetics by the double exponential model and conventional kinetic models. Phthalocyanine is formed through the cyclotetramerization of various phthalic acid derivatives including phthalonitrile, diiminoisoindole, phthalic anhydride, and phthalimides. Benten, H., Kudo, N., Ohkita, H. & Ito, S. Layer-by-layer deposition films of copper phthalocyanine derivative; their photoelectrochemical properties and application to solution-processed thin-film organic solar cells. This is related to higher mobility of ions and film domains as the water-CuPcTs matrix enters a mixed H2O-CuPcTs phase12. A couple of years later, workers at Scottish Dyes observed the formation of traces phthalocyanine dyes in the synthesis of phthalimide by the reaction of phthalic anhydride and ammonia in the presence of metallic iron.

The combination of these results strongly suggests that H2O adsorption on CuPcTs can be described in terms of two sequentially-occurring PFO reaction steps. [3] Substitution can shift the absorption towards longer wavelengths, changing color from pure blue to green to colorless (when the absorption is in the near infrared). It is potentially suited for organic solar cells because of its high chemical stability and uniform growth. I.I. Scheme for water uptake into CuPcTs domain. )4.

Bismuth oxychloride (BiOCl)/copper phthalocyanine (CuTNPc) heterostructures immobilized on electrospun polyacrylonitrile nanofibers with enhanced activity for floating photocatalysis. Since electrical conductance (1/R) differs from electrical conductivity () by a constant factor related to electrode spacing (\(\rho =RA/l\), where A is the cross-sectional electrode area and l is the channel length between electrodes), the effect of humidity on conductance can be used as an equivalent measure of its effect on conductivity.

BODIPY is thermodynamically not feasible, the singlet ZnPc decayed to populates the triplet ZnPc, in addition to the grounds Electrochemical impedance spectroscopy (EIS) was performed using a Zahner IM6 electrochemical workstation. The pyrrole-like rings within H2Pc are closely related to isoindole. The transition in C1 occurs in the same RH range (5070%) at which significant changes in optical constants, bandgap, and film thickness occur. Both R1 and R2 undergo slight changes at RH 57% (FigureS10). The Journal of Physical Chemistry B for more information. CAS Phthalocyanine and derived metal complexes (MPc) tend to aggregate and, thus, have low solubility in common solvents.

Water exposure leads to significant decreases in k between 550 and 650nm and decreases in n between 450 and 900nm. HHS Vulnerability Disclosure, Help 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).

Difficulty was experienced in forming stable dispersions with the first alpha forms, especially in mixtures with rutile titanium, where the blue pigment tended to flocculate. 81, 4552 (2009). 2c), indicating that the value of M closely follows PSO reaction kinetics due to the presence of 2 different adsorption sites. 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. 0xSp22$ [17] The color is due to a * electronic transition, with max 610nm.

Error bars correspond to noise in the measured QCM signal. [17] The abbreviation "CuPc" is also used.[18]. It is highly valued for its superior properties such as light fastness, tinting strength, covering power and resistance to the effects of alkalis and acids. Frequency shift of the QCM crystals was converted to mass change using the well-known Sauerbrey equation25. Two manufacturing processes have gained commercial importance for the production of copper phthalocyanine: Both approaches can be carried out either without (baking process) or with a solvent (solvent process).
