Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs

open access: yesAdvanced Optical Materials, EarlyView.
The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.

Retrospective time-trend study of polybrominated diphenyl ether and polybrominated and polychlorinated biphenyl levels in human serum from the United States.

open access: yesEnvironmental Health Perspectives, 2004
Six polybrominated diphenyl ethers (PBDEs), one hexabromobiphenyl [polybrominated biphenyl (PBB)], and one hexachlorobiphenyl [polychlorinated biphenyl (PCB)] were measured in 40 human serum pools collected in the southeastern United States during 1985 ...

Torsional effects in strong-field ionization of molecules

open access: yesPhysical Review Research, 2019
We investigate how the ionization rate of molecules consisting of a pair of phenyl rings depends on the torsional dihedral angle between these two rings. We consider different orientations of the molecules with respect to the external field direction and

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

open access: yesAdvanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Microwave Assisted Synthesis of N-Substituted-7-hydroxy-4-methyl-2-oxoquinolines as Anticonvulsant Agents

open access: yesE-Journal of Chemistry, 2011
The reaction of resorcinol with ethylacetoacetate yielded the 7-hydroxy-4-methyl coumarin (1), which on treatment with benzidine gives 1-(4ʹ-amino-biphenyl-4-yl)-7-hydroxy-4-methyl-1H-quinolin-2-one (2). 1-{4ʹ-[(Substituted benzylidene)-amino]-biphenyl-4-
