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. 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 \(\,{k}_{1-2}\).

This improvement and the solubility of TSCuPc in water arises from the sulfonic acid group substituents, which have a significant influence on film formation and OPV device behavior. The quaternary ammonium salts of these sulfonic acids are used as solvent dyes because of their solubility in organic solvents, such as Solvent Blue 38 and Solvent Blue 48. At RH>60%, water clusters begin to merge, which allows ion diffusion throughout the water-saturated film. It is a standard pigment used in printing ink and the packaging industry.

Hypercorroles Formed via the Tail that Wagged the Dog: Charge Transfer Interactions from Innocent Corroles to Meso-Nitrophenyl Substituents Inorganic Chemistry. 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. Higher yields may be achieved with the solvent process (> 95%) than with the baking process (70 to 80%), so that the solvent process has initially simulated more interest. Journal of The Electrochemical Society. 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-)4 ions. The electronic absorption spectrum of CuPc has two prominent features which arise from * transitions: the Q band (~600750nm), associated with a1u to eg Here, sensitivity refers to the smallest RH changes detectable by the particular measurement technique at a given water vapor pressure P/P0 as estimated from the signal to noise ratio (SNR) for each response. This result, related to the behavior of n and k, is caused by dielectric screening of CuPcTs by water. ( a ) Estimated RH sensitivity achieved by, MeSH 97, 318324 (2012).

[17] The color is due to a * electronic transition, with max 610nm. At RH>60%, water saturation of CuPcTs domains leads to dielectric screening of the CuPcTs electronic charge carriers by dipolar water layers, which results in dramatic decreases in the values of n and k.
