Nierstrasz, Scientific Reports 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. Upon formation of H2O multilayers and merging of adjacent adsorbed H2O clusters, interactions between mobile Na+ ions, CuPc(SO3 contributed to analysis of results and conception and design of experiments. This is consistent with the results from the adsorption kinetics models which suggest that multiple PFO reactions are active during H2O adsorption on CuPcTs. Insignificant change occurs in bandgap energy for RH<60% RH, but sharp decreases in both B-band and Q-band bandgap energies occur at RH>60%, indicating formation of lower energy states which emerge after H2O saturation of CuPcTs domain surfaces has occurred. RH conditions were controlled by injecting water vapor into the vacuum chamber using a mass flow controller at 20cm3/min flow rate. The basic copper phthalocyanine has a very low solubility in water (0.009 mg/L) and in octanol (0.0004 mg/L).

The CuPcTs optical thickness change also exhibits slight (~10nm) hysteresis in the 5080% RH range between adsorption and desorption processes. They feature four pyrrole-like subunits linked to form a 16membered inner ring composed of alternating carbon and nitrogen atoms. Error bars correspond to linear fitting errors. Changes in the slopes of n and k with RH (FigureS5a) indicate the presence of a 2-step process. Spectral and RH dependence of 2 is shown in FigureS11. CuPc (copper phthalocyanine) was first prepared in 1927 by the reaction of copper(I) cyanide and o-dibromobenzene, which mainly produces colorless phthalonitrile as well as an intensely blue by-product. Biler, M. et al. The presence of pinholes and large (10100nm diameter) interstitial spaces between grains result in high film porosity and surface area which allows for rapid H2O diffusion into the bulk film. Figure6a summarizes the results of CuPcTs RH sensitivity as estimated using different measured modes. 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. 1d). The most common phthalocyanine-based humidity sensors rely on measurement of direct-current (DC) electrical resistivity measurements. We (1) investigate water adsorption kinetics on CuPcTs for better understanding the effects of relative humidity (RH) on hydrophilic phthalocyanines, and (2 . *TCI frequently reviews storage conditions to optimize them.

As a result, MPc-based organic solar cells with power conversion efficiencies at or below 5% have been developed. Exponential heterogeneous (multi-site) adsorption kinetic models are of the form \(\,{\rm{\Delta }}M={M}_{{\rm{0}}}+{\sum }_{i=1}^{n}{A}_{i}{{\rm{e}}}^{-t/{{\rm{\tau }}}_{i}}\), where \(n\) is the number of active sites, \({A}_{i}\) corresponds to the relative amount of mass adsorbed at Site-i, and \({{\rm{\tau }}}_{i}\,\,\)is the inverse of the adsorption rate constant at Site-i.

Kim KN, Lee SK, Lee HY, Kim DH, Lee JC, Moon SJ. 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. Unsubstituted phthalocyanines strongly absorb light between 600 and 700nm, thus these materials are blue or green. 146, 794799 (1999). Google Scholar.

Items from Japan stock are able to ship from a US warehouse within 2 weeks. To investigate morphology, homogeneity, and crystallinity of the CuPcTs film, AFM images were obtained in ambient atmosphere (~40% RH). Zhang T, Zhao S, Piao L, Xu Z, Liu X, Kong C, Xu X.

Those phases can be distinguished by the overlap of their neighboring molecules. 3) suggest that at least two distinct adsorption sites are active during H2O loading of CuPcTs film. Reaction models show that H2O undergoes 2-site adsorption which can be represented by a pair of sequentially-occurring pseudo-first order reactions. Today, there are even more isomeric forms available. 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.

The ratio of A2/A1 corresponds to the relative activity of adsorbates at site 2 relative to site 1, while 2/1 corresponds to timescale associated with the adsorption rate at site 2 relative to the adsorption rate at site 1. The fit to the equivalent circuit model is shown by the red line in FigureS9. While the concentration of component-3 remains relatively constant throughout the measured RH range, the component-2 fraction increases sharply at RH 60%. 15 (IEEE).

At low RH, the films dielectric response to H2O adsorption is weak, since delocalization of -electrons in the phthalocyanine ring allows high electronic polarizability and dielectric constant37.

Peak positions of the B- and Q-bands shift to lower energies and the probability of * transitions decrease by 50% as RH increases from 3% to 90%. Similar behavior is observed in the RH dependence of k (FigureS5b). Finally, we demonstrate the value of using a multi-modal approach for understanding mechanisms of sensing and referencing optical and electrical changes to the mass of adsorbed water on the surface of the sensor, as well as identification of the most sensitive detection modes for analyte identification. CuPcTs films were deposited from solution on pre-cleaned 5MHz AT-cut gold-coated quartz crystal microbalance (QCM) crystals with 1cm2 active electrode area, conductive n-doped SiO2 substrates, and undoped SiO2 substrates with pre-patterned gold interdigitated electrodes (10nm thickness, 2m spacing, 100 digits per electrode).
