“…The diffraction pattern could be assigned with an error of less than 3.1% by using the lattice parameters of no-counter-component-containing bulk phthalocyanine crystals, i.e., those of Co(Pc)(CN) 2 . 25 We found that the synthesized nanocrystals were identical in structure to completely one-electron-oxidized bulk crystals of Co(Pc)(CN) 2 .…”

“…Inabe et al have reported that the bulk electrocrystallization of this material can yield several bulk single crystals that consist of completely one-electron-oxidized neutral radical molecules of [Co(Pc)(CN) 2 ]. 25,26 In these bulk crystals, phthalocyanine is present in a "slipped-stack" arrangement. This slipped-stack arrangement varies with the counter components of the crystals.…”

“…This slipped-stack arrangement varies with the counter components of the crystals. 25 These crystals exhibited a resistivity of 10 1 -10 4 U cm at room temperature. The temperature dependence of their resistivity is a reection of their semiconducting nature.…”

“…4. 25,32 In view of this result, it can be assumed that the isotropic conduction of electrons in the synthesized nanocrystals will be greater than that in materials with a onedimensional p-stacking structure. By reusing the two electrochemical electrodes as source and drain electrodes, a two-terminal device could be readily fabricated through a one-pot process.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…When the crystal solvent is CHCl 3 or DMSO, 2D sheets of Co(Pc)(CN) 2 units, as in PXX-2:1, were found in the neutral radical crystals of Co(Pc)(CN) 2 ·2CHCl 3 (Figure c) and Co(Pc)(CN) 2 ·2DMSO …”
