Single-crystalline 9,10-bis(phenylethynyl)anthracene (BPEA) nanowires are promising building blocks for all-organic ultraviolet (UV) photodetectors owing to their environmental stability and efficient absorption of UV radiation. However, many the intrinsic properties BPEA become largely smeared when they adopt disordered ensembles. In this study, by exploiting exceptional graphoepitaxial effect hydrophobic parallel nanogrooves, self-aligned planar with high crystallinity chemical purity...
Abstract The simultaneous control of the orientation and position organic semiconductor nanowires remains a major challenge when integrating them into monolithic devices. In this study, tris(8‐hydroxyquinoline)aluminum(III) (Alq3) molecules are self‐assembled single‐crystalline with consistent predictable positions by selective‐area graphoepitaxial growth. nanowire is determined parallel nanogrooves on periodically modified faceted sapphire surface, simultaneously defined using shadow mask....
A novel hole-transport material, 1,3-diphenyl-5-(9-phenanthryl)-4,5-dihydro-1H-pyrazole (DPPhP), was synthesized and fully characterized. The crystal structure of DPPhP determined by X-ray diffraction analyses. DSC AFM analysis demonstrate that has a high Tg 96 °C good film forming ability. performance examined fabricating multilayer device with ITO/DPPhP (60 nm)/AlQ nm)/LiF (0.8 nm)/Al, using as the layer along an emitting-material, tris-(8-hydroxyquinolino)aluminium (AlQ). Both brightness...

Photorefractive four-wave mixing (FWM) and photoconductivity properties of two new polymers are investigated. One polymer is composed photoconducting poly(n-vinylcarbazole) (PVK), photosensitizing 2,4,7-trinitro-9-fluorenone (TNF), optically nonlinear 4-(dicyanovinyl)-N.N-diethylaniline (DCVDEA). Its FWM diffraction efficiency response time as a function of, respectively, electric field writing intensity have been determined. With an 80 micrometer thick film, 7.4 by 10<SUP>-4</SUP> has...
