115, 2492024930 (2011). ( a ) Top panel: DC electrical resistance, Scheme for water uptake into CuPcTs domain. Water Research The presence of H2O at SO3Na groups induces salt dissociation, leading to formation of Na+ and CuPc(SO3 Scheme for water uptake into CuPcTs domain. 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). [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). Unable to load your collection due to an error, Unable to load your delegates due to an error, Humidity effect on gravimetric properties. (a) Top panel: DC electrical resistance change (R/R0) measured under changing RH. Zhang TH, Zhao SL, Piao LY, Xu Z, Kong C. Guang Pu Xue Yu Guang Pu Fen Xi. 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. Film capacitance (C1) exhibits a sharp change at RH 60% (Fig. Those phases can be distinguished by the overlap of their neighboring molecules. ( a ) AFM image of CuPcTs film., Kinetics modelling. Combining gravimetric and optical techniques, we demonstrate the possibility of humidity sensing in the 095% RH range with 2.5% resolution.

Sign up for the Nature Briefing newsletter what matters in science, free to your inbox daily. PCA results indicate that significant changes in optical constants which occur near 6070% RH are a result of the emergence of a secondary process which becomes active after significant H2O adsorption has taken place in the film, which suggests that the secondary principal component is related to dielectric screening caused by H2O saturation of CuPcTs domains. It is a standard pigment used in printing ink and the packaging industry. To obtain DOI: 10.1021/acs.inorgchem.2c03425. 2017 Nov 28;11(11):11118-11126. doi: 10.1021/acsnano.7b05264. The beta form was more stable, as was the improved stabilized alpha form. All measurements were performed at 270.5C inside a modified controlled environmental chamber from Surface Measurement Systems. * orbital transitions, and the B (Soret) band (~300450nm), associated with a2u to eg Registered Trademark. The choice of the solvent is very important, as it plays a significant role in the generation of impurities. Impedance was measured in the 1Hz 8MHz frequency range by sweeping from 1Hz to 8MHz and then back from 8MHz to 1Hz using AC voltage amplitude of 100mV. 0. Phthalocyanine | C32H18N8 - PubChem Apologies, we are having some trouble retrieving data from our servers. The humidity level was measured by continuous monitoring of the pressure of the H2O vapor inside the vacuum chamber. (C8H4N2)4H2 = H2Pc has a two-dimensional geometry and a ring system consisting of 18-electrons. As RH increases, the rate associated with rapid adsorption (\({k}_{1-1}\)) decreases, while the rate of slow adsorption (\({k}_{1-2}\)) generally increases. Kato, K. et al. 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 1997-2023 American Elements. The rate constant \({k}_{2}\) was extracted and compared to \({k}_{1-1}\) and \({k}_{1-2}\) (FigureS4). Please note that the latest information on the storage temperature for the products is described on our website. 2a. It is potentially suited for organic solar cells because of its high chemical stability and uniform growth. Humidity effect on optical properties. [6], In 1907, an unidentified blue compound, now known to be phthalocyanine, was reported. 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.

C.B. (a) AFM image of CuPcTs film. 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 \(\,{k}_{1-2}\). Both porphyrins and phthalocyanines function as planar tetradentate dianionic ligands that bind metals through four inwardly projecting nitrogen centers.

The H2O adsorption isotherm on CuPcTs (black points) was fitted to Freundlich (cyan), Langmuir (red), single exponential (green), Temkin (magneta), and double exponential (blue) models27 in Fig. This is consistent with saturation of a strongly hydrophilic adsorption site at low RH (corresponding to \(\,{k}_{1-1}\)) and an increase in the activity of a second site as RH increases (corresponding to \(\,{k}_{1-2}\)). 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.

Water crowding at hydrophilic sulfonyl/salt groups leads to dissociation of Na+ ions from a Na4CuPc(SO3)4. Phthalocyanine and derived metal complexes (MPc) tend to aggregate and, thus, have low solubility in common solvents. (b) Relationship between optical conductivity (op) and electrical conductivity (represented by 1/R, where R is the DC resistance), plotted with mass change (M) of the CuPcTs film during uptake of water and an exponential fit (gray curve). During the first step, H2O molecules undergo rapid adsorption at hydrophilic sulfonyl/salt groups near CuPcTs domain surfaces. All Rights Reserved BNP Media. Muckley, E.

Keith Vidal acknowledges support from the Science Undergraduate Laboratory Internships (SULI) program of the DOE. We use several isotherm models to examine the kinetics of water adsorption, which reveals a complex adsorption mechanism that involves at least two different adsorption sites, including a dominant process which is active in the entire measurement range (~095% RH) and one which becomes active for RH>60%. Phthalocyanine and derived metal complexes (MPc) tend to aggregate and, thus, have low solubility in common solvents. 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.
