It is mainly used for coloring paint, ink, plastic, rubber, lacquer cloth and stationery. Such complexes are formally derivatives of Pc2, the conjugate base of H2Pc. 9, 970984 (2012). 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. Application Dispose of contaminated gloves after use in accordance withapplicable laws and good laboratory practices. 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. 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. Fitting was performed on impedance spectra measured from 0% to 90% RH. Error bars are propagated double exponential fitting errors. Barrett, M., Borkowska, Z., Humphreys, M. W. & Parsons, R. Ellipsometry of thin films of copper phthalocyanine. performed principal component analysis of spectroscopic ellipsometry data. The average height visible in the AFM image is ~21nm, which suggests that pinholes visible in the image penetrate to a depth of at least half of the film thickness. The CuPcTs-H2O interaction can be tracked using a combination of gravimetric, optical, and electrical sensing modes, enabling accurate (2.5%) sensing in the ~095% RH range with a detection limit of less than 0.1% RH. Both ratios \({{\rm{\tau }}}_{2}/{{\rm{\tau }}}_{1}\) and \({k}_{1-2}/{k}_{1-1}\) increase linearly from ~0.03 to ~0.1 as RH increases from 10% to 95%, which suggests that the double exponential behavior modelled in Fig. Phys. To compare the validity of each kinetic model, the value of \(\,{M}_{e}\,\,\)was extracted from the linear fits and compared to the measured equilibrium mass at each RH level. When CuTCPc acts as an interlayer, the performance of the device ITO/CuTCPc/P3HT:PCBM/Al is improved: J(SC) increases to 3.12 mA/cm2, V(OC) increases to 0.59 V, FF increases to 33.8%, and the corresponding nu is 0.62%. Since the electron transfer from the singlet ZnPc to, BODIPY is thermodynamically not feasible, the singlet ZnPc decayed to populates the triplet ZnPc, in addition to the grounds, state. 97, 318324 (2012). 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.

The absorption spectrum of ZnPc-BODIPY pentad covers most of the visible region As RH increases, contribution of the first adsorption mechanism (water on CuPcTs) decreases, and a secondary process (water adsorption on H2O-CuPcTs) becomes prevalent. Many phthalocyanine compounds are, thermally, very stable and do not melt but can be sublimed. Hybrid Polymer/Metal-Organic Framework Films for Colorimetric Water Sensing over a Wide Concentration Range. 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 \(\,{k}_{1-2}\).

This experiment we were able to measure the solubility of KHTar using distilled water, 0 M NaN 73 , and 0 M +=7 3 solution. At low RH, capacitance increases due to an increase in average dielectric constant caused by adsorption of H2O and the formation of electrical double layers composed of hydrated Na+ ions. Phase Transition of Graphene-Templated Vertical Zinc Phthalocyanine Nanopillars. We (1 . and transmitted securely. Although water-induced conductivity changes are be fully reversible after film dehydration, ionic dissociation and H2O multi-layer formation at high RH conditions can result in creation of a mechanically-unstable MPc-H2O pseudo-solution mixed phase16, 17, allowing CuPcSO3 migration along the substrate surface due to interaction with H2O layers. The pigment is insoluble and has no tendency to migrate in the material. The increased mobility facilitates the breakdown of electrical double layers and a resultant decrease in capacitance.

Lines show linear fits. CAS This trend is opposite to that of n (optical-mode sensing), which exhibits high RH dependence at P/P0>0.6 (Figs3a and S5a) and thus represents the most sensitive (<2% RH) detection mode at high RH. Such compounds are prepared by treating CuPc with chlorine, bromine or oleum. 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 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. At ~60% RH (represented by dotted contour line), optical conductivity exhibits a sharp decrease due to the onset of dielectric screening of the CuPcTs domains by a water meniscus and hydrated ionic double layer structures32, 35, 36. The description is analogous to that for copper porphyrins, which are also formally derived by double deprotonation of porphyrins.

Electrical properties and gas response in alternate layer-by-layer films of copper phthalocyanine dyes. The basic copper phthalocyanine has a very low solubility in water (0.009 mg/L) and in octanol (0.0004 mg/L). 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. The absorption spectrum of ZnPc-BODIPY pentad covers most of the visible region, (ca. While optical response of sulfonated phthalocyanines has been well-studied in solution, less information is available about water interaction with solid films15, 19. Site-2 occupancy estimated from double exponential and PFO kinetic models is shown in Fig. Water Solubility <0.1 g/100 mL at 20 C: max: 602nm(CHCl3)(lit.)

This approach involves heating phthalonitrile with a copper salt, usually copper(I)chloride at 200C to 240C. It is available in both alpha and beta forms. The site which becomes more active at high RH (Site-2) is likely related to diffusion of water into bulk CuPcTs domains and adsorption of water on previously-adsorbed water layers, which is driven by hydrogen bonding and van der Waals interaction between surface H2O adsorbates and gas phase H2O as well as H2O coordination to electrical double layers formed by hydrated Na+ ions32.

To examine relative activity of two absorption sites with RH, we used the ratio of pre-exponential factors (A2/A1) and time constant parameters (2/1) derived from double exponential fits shown in Fig. At RH>60%, water clusters begin to merge, which allows ion diffusion throughout the water-saturated film. 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). Similar behavior is observed in the RH dependence of k (FigureS5b). It is a standard pigment used in printing ink and the packaging industry.
