CAS It is present in a wide variety of products,[20] such as color deposition hair conditioner,[21] eye patches, parfum, shampoo, skin-care products, soap, sunscreen, tattoo ink,[22] toothpaste. Approximately 25% of all artificial organic pigments are phthalocyanine derivatives. But in this case the final product will have a statistical average of 0.5 chlorine atoms per copper phthalocyanine molecule (semichloro copper phthalocyanine). Other phthalocyanine derivatives such as sulphonic acids, sulphonamides, sulphonium salts are also widely used to make special grades of pigments for specific applications. 
Unsubstituted copper phthalocyanine blue exists in different crystal modifications. Photoinactivation of bacteria. 1a). Sappok, R. J.O.C.C.A. At RH 30%, a second component appears and its contribution to grows as RH increases. Mobile Na+ ions are represented by purple (+) symbols while CuPc(SO3 [23] and even turf colorants [24]. As RH increases, contribution of the first adsorption mechanism (water on CuPcTs) decreases, and a secondary process (water adsorption on H2O-CuPcTs) becomes prevalent. CuPc has often been investigated in the context of molecular electronics. In particular, we find that mass-based measurements achieve the highest resolution at RH<50% while optical techniques achieve the highest resolution at RH>50%. 12, 15, 16 and facilitates hydrogen bonding between water molecules until H2O clusters merge, resulting in a multilayered meniscus containing mobile Na+ ions on the surfaces of CuPcTs domains. However, recents trends show a reverse tendency for the baking process mainly on the grounds of economical and ecological concerns (solvent-free, shorter lead time).

C. et al. Error bars are propagated from errors in fitting to equivalent circuit model. The CPC pigment has a limited solubility in aromatic solvents and due to this the molecules move continuously from the particle surface of a form into the solvent and from the solvent to the particle surface. Figure4a shows relative changes in the DC resistance (R/R0) as RH is increased. 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. The final product thus formed will contain an average of one chlorine atom per CPC molecule (Scheme 4b). The degree of agitation, rate of addition of the dissolved CPC, temperature and surfactant, etc., are the key parameters at the hydrolysis stage, which eventually determine the particle size of the finished pigment. [32] Copper phthalocyanine dyes are produced by introducing solubilizing groups, such as one or more sulfonic acid functions. 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 newly synthesized compounds (BS, BS-1, BS-1-CN), copper(II), manganese(III), phthalocyanines (BS-1-Cu, BS-1-Mn) and their water soluble derivatives (BS-1-CuQ, BS-1-MnQ) were characterized by standard methods.All steps of the synthetic procedures were given in Figs.

The two well-known derivatives are haemoglobin, the iron III complex and chlorophyll, the magnesium complex. *TCI frequently reviews storage conditions to optimize them. While optical response of sulfonated phthalocyanines has been well-studied in solution, less information is available about water interaction with solid films15, 19. 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. This result, related to the behavior of n and k, is caused by dielectric screening of CuPcTs by water. 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. 517, 20162022 (2009). 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).

WebName matches: triphenyltetrazolium chloride phthalocyanine blue. 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. 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. 7, 13651370 (2005). The choice of the derivative, surfactant and the conditions employed at the surface treatment stage are the key factors in determining the performance of the finished product in various application media.
