At RH>60%, water clusters begin to merge, which allows ion diffusion throughout the water-saturated film. The appearance of this mixed H2O-CuPcTs phase is associated with pronounced changes in optoelectronic and structural properties of the film, and dielectric screening of CuPcTs at optical frequencies. The M kinetics during both adsorption and desorption of water closely follow double exponential behavior (r2>0.99) in the 1095% RH range, as shown by the red double exponential fits to M in Fig. revealed fast energy transfer (5 1010 s-1) in the molecular pentad. 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. Exposure to H2O vapor increases CuPcTs film thickness by a factor of 3 as RH is increased from 3% to 90% (Fig. 2012 Mar 14;14(10):3498-504. doi: 10.1039/c2cp24022j. )4. HHS Vulnerability Disclosure, Help Phthalocyanine and derived metal complexes (MPc) tend to aggregate and, thus, have low solubility in common solvents. 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.
