Abstract: Three isomeric derivatives of 2,2',2″-(1,3,5-benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi) bearing ethyl groups on the N-phenyl moieties were synthesized to elucidate the effects of intramolecular interactions on spontaneous orientation polarization (SOP) in thin films. The films of the TPBi… read more here.

Abstract: We report an in situ high-pressure (0-30.24 GPa) optical study of the 2D ReS2 crystal under four specific configurations of sample orientation and laser polarization. Unlike the horizontal measurement configuration that has been widely used,… read more here.

DOI: 10.1126/sciadv.abb2659
Abstract: Spontaneous orientation polarization in OLEDs reduces efficiency but can be eliminated by heating during film deposition. The efficiency of organic light-emitting devices (OLEDs) is often limited by roll-off, where efficiency decreases with increasing bias. In… read more here.
