Novel photoactive fluorene-based terpolymers incorporating carbazole for photovoltaic application. 2) and principal component analysis (Fig. 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 \(\,{k}_{1-2}\). 2022. [5] They are less thermally stable and often can not be sublimed. Aqueous solubility of copper phthalocyanine-3,4,4,4-tetrasulfonic acid tetrasodium salt (CuPcTs) enables fabrication of flexible electronic devices by low cost inkjet printing. The phase has a larger overlap and thus, a smaller Cu-Cu spacing (~3.8) compared to the phase (~4.8). Water Solubility <0.1 g/100 mL at 20 C: max: 602nm(CHCl3)(lit.) A combination of gravimetric and optical detection modes was selected to enable the highest resolution (2.5% RH) humidity sensing in the entire 095% RH range, with gravimetric detection as the most sensitive mode for RH <50% and optical detection as most sensitive for RH >50%. [29] The VOC is significantly larger than that produced by similar cells based on the commonly studied copper phthalocyanine (CuPc)/C60 heterojunction (VOC = 0.46 V). 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. FOIA CuPc can be easily processed into a thin film for use in device fabrication, which makes it an attractive qubit candidate.[31].

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. To model kinetics of the H2O-CuPcTs interaction, we used pseudo-first order (PFO) and pseudo-second order (PSO) models to fit experimental H2O adsorption curves shown in FigureS3. The choice of the solvent is very important, as it plays a significant role in the generation of impurities. All Sponsored Content is supplied by the advertising company.
