Abstract:An alternating block copolymer, poly(1,8‐octanedioxy‐2,6‐dimethoxy‐1,4‐phenylene‐1,2‐ethenylene‐1,4‐phenylene‐1,2‐ethenylene‐1,4‐phenylene‐1,2‐ethenylene‐3,5‐dimethoxy‐1,4‐phenylene), 1, was synthesized, and characterized using Fourier transform infrared spectroscopy, nuclear magnetic resonance, gel permeation chromatography differential scanning calorimetry ultraviolet and elemental analysis. Light‐emitting single‐layer test diodes using this soluble, processible copolymer as the active layer (i.e. indium tin… Show more
“…Absorption spectra obtained in dilute chloroform (Figure ) are nearly the same, showing that linkage of the chromophores in 2 does not lead to their aggregation. The absorption maxima of 1 and 2 are similar to those observed for the PPV 2.5-mer 7 and related copolymer 8 , which have a central phenylene unit instead of the fluorene unit. 2 UV-vis spectra for 1 () and 2 (- - -) in chloroform at room temperature; spectra are normalized for comparison.…”
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.

“…The spectra are similar to one another, but the bands for the segmented oligomeric system are somewhat blue-shifted relative to the corresponding molecular spectra. The related segmented copolymer 3.5PV4PE also exhibits a (smaller) absorption blue shift relative to the spectrum of its analogous molecular chromophore. The blue shifts in the segmented systems by comparison to the molecular systems may indicate π-system torsion due to the effect of the linker groups, but there is no other direct evidence for this at this time.…”

“…Cyano-substituted PPV structures have been developed in which the cyano group is attached to the vinylene moiety and alkoxy groups (such as OC 6 Hi 3 ) are substituents to the phenyl ring to provide solubility.The synthesis, the theoretical investigations of the effect of derivatization, the effects of the inclusion of alkoxy-substituted thiophene groups in the repeating unit or replacing the phenyl ring, the emission mechanism in solution and in the solid state using time resolved spectroscopy, and the effects of the substitution on chain packing and optical properties of 2,5 alkoxy substituted cyano PPV's have all been studied. 4 We have synthesized a new class of cyano-substituted light emitting polymers, in which the chromophores are isolated from each other through a flexible non-conjugated spacer.…”
