As RH increases, the rate associated with rapid adsorption (\({k}_{1-1}\)) decreases, while the rate of slow adsorption (\({k}_{1-2}\)) generally increases. Agranovich, V. M. Excitations in organic solids. During the first step, H2O molecules undergo rapid adsorption at hydrophilic sulfonyl/salt groups near CuPcTs domain surfaces. Integration of an M-phthalocyanine layer into solution-processed organic photovoltaic cells for improved spectral coverage. PMC 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). Water Solubility <0.1 g/100 mL at 20 C: max: 602nm(CHCl3)(lit.) The most common phthalocyanine-based humidity sensors rely on measurement of direct-current (DC) electrical resistivity measurements.

Unsubstituted phthalocyanines strongly absorb light between 600 and 700nm, thus these materials are blue or green. Thin Solid Films Here we employ multi-modal probing of the CuPcTs response to water vapor by connecting gravimetric, electrical, and optical techniques to relate the quantity of adsorbed water to changes in optical constants, electrical resistance, and capacitance of the film under changing RH conditions. for more information.

[35], CuPc crystallizes in various forms (polymorphs). In general, a crude copper phthalocyanine is produced by reacting phthalic anhydride, urea, copper/copper salt and ammonium molybdate (catalyst) in high-boiling solvent such as o-nitrotoluene, trichlorobenzene or alkyl benzenes. Error bars correspond to errors propagated from fitting to the Lorentz oscillator model. [11] Alternatively, heating phthalic anhydride in the presence of urea yields H2Pc. Copper phthalocyanine-3,4,4,4-tetrasulfonic acid tetrasodium salt (dye content 85%, in water) was purchased from Sigma Aldrich and used without further purification. The PSO model predicts the equilibrium mass with <3% error, while the double exponential model achieves <5% error. 74160.

RH levels inside the flow cell were controlled using an L&C Science RH-200 humidity generator and measured with an additional humidity probe at the outlet of the flow cell. 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). Results from double exponential and PFO kinetic models suggest that at least 2 distinct sites are active during H2O adsorption on CuPcTs. Fit lines correspond to colors used in the bar graph.

Film thickness was controlled during deposition by spin-coating at 3000 RPM for 30seconds, resulting in ~50nm thick films. The phase has a larger overlap and thus, a smaller Cu-Cu spacing (~3.8) compared to the phase (~4.8). One of the most common donor/acceptor architectures is CuPc/C60 (buckminsterfullerene) which rapidly became a model system for the study of small organic molecules.

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. NY Times Paywall - Case Analysis with questions and their answers. We (1) investigate water adsorption kinetics on CuPcTs for better understanding the effects of relative humidity (RH) on hydrophilic phthalocyanines, and (2) assess CuPcTs as a humidity-sensing material. 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%. 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. 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%.
