CuPc can be easily processed into a thin film for use in device fabrication, which makes it an attractive qubit candidate.[31]. [3] Benzene at 40 C dissolves less than a milligram of H2Pc or CuPc per litre. Spectral and RH dependence of 2 is shown in FigureS11. Frequency shift of the QCM crystals was converted to mass change using the well-known Sauerbrey equation25. In the approximation $\,[{M}_{e1}-{M}_{t1}]\approx [{M}_{e2}-{M}_{t2}]$, the pseudo-second order (PSO) rate equation34 becomes $d{M}_{ad}/dt=\,{k}_{2}{({M}_{e}-{M}_{t})}^{2}$. Bethesda, MD 20894, Web Policies Copper phthalocyanine (CuPc), also called phthalocyanine blue, phthalo blue and many other names, is a bright, crystalline, synthetic blue pigment from the group of phthalocyanine dyes. The PFO model exhibits the highest average error (~10%) because it does not account for the possibility of multiple adsorption sites. artificial photosynthetic systems.

The https:// ensures that you are connecting to the Its electron configuration is [He]2s22p3. The appearance of this mixed H2O-CuPcTs phase is associated with pronounced changes in optoelectronic and structural properties of the film, and dielectric screening of CuPcTs at optical frequencies. It is the seventh most abundant element in the universe and it constitutes 78.09% (by volume) of Earth's atmosphere. : 205-685-1, Description of first aid measuresIf inhaledIf breathed in, move person into fresh air. Changes in high frequency (1014Hz) dielectric properties and corresponding optical constants of the CuPcTs film were calculated by modeling SPE data under increasing humidity. )4. 156, 210 (2010). 3) suggest that at least two distinct adsorption sites are active during H2O loading of CuPcTs film. The phase has a larger overlap and thus, a smaller Cu-Cu spacing (~3.8) compared to the phase (~4.8). 566, 2232 (2012). 1980;127:15061517. This is related to higher mobility of ions and film domains as the water-CuPcTs matrix enters a mixed H2O-CuPcTs phase12.

At RH>60%, the formation of H2O layers containing mobile Na+ ions can increase the effective contact area at electrodes and result in improved electronic transport by allowing charge carriers to hop between hydrated ionic structures consisting of coordinated Na+ and dipolar H2O, leading to a decrease in R2. Applied surface science. The value of R/R0 exhibits roughly exponential behavior, reaching equilibrium at ~50% RH, which suggests that water adsorption alters DC conductivity of the film only before water saturation of CuPcTs domain surfaces has occurred.

Water confined in films of sulphonated phthalocyanines. The origin of the word copper comes from the Latin word 'cuprium' which translates as "metal of Cyprus," as the Mediterranean island of Cyprus was known as an ancient source of mined copper.. See more Nitrogen products. 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. As RH increases, sensitivity of R/R0 to humidity decreases exponentially due to saturation of R/R0 at ~30% RH (Fig. Harrington, D. A. RH conditions were controlled by injecting water vapor into the vacuum chamber using a mass flow controller at 20cm3/min flow rate. Excludes regulated items and items that ship on ice.
