《Highly efficient yellow phosphorescent organic light-emitting diodes with novel phosphine oxide-based bipolar host materials》 was written by Zhang, Song; Xu, Qiu-Lei; Xia, Jing-Cheng; Jing, Yi-Ming; Zheng, You-Xuan; Zuo, Jing-Lin. Name: (3-Bromophenyl)diphenylphosphine oxide And the article was included in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2015. The article conveys some information:
Two bipolar host materials, (4-((4-(naphthalen-1-yl(phenyl)amino)naphthalen-1-yl)(phenyl)amino)phenyl)diphenylphosphine oxide (POpN) and (3-((4-(naphthalen-1-yl(phenyl)amino)naphthalen-1-yl)(phenyl)amino)phenyl)diphenylphosphine oxide (POmN), comprising a hole-transporting N1-(naphthalen-1-yl)-N1,N4-diphenylnaphthalene-1,4-diamine (NPNA2) donor and an electron-transporting phosphine oxide (PO) acceptor at different positions of the Ph bridge were synthesized. POpN (glass transition temperature Tg = 119°) and POmN (Tg = 115°) exhibit high morphol. stability. Two yellow phosphorescent organic light-emitting diodes (PhOLEDs, ITO (indium Sn oxide)/TAPC (1,1-bis[4-(di-p-tolylamino)phenyl]cyclohexane, 40 nm)/POpN or POmN: Ir(bt)2(acac) (bis(2-phenylbenzothiozolato-N,C2′)iridium(acetylacetonate), 15%, 20 nm)/TmPyPB (1,3,5-tri(m-pyrid-3-yl-phenyl)benzene, 40 nm)/LiF (1 nm)/Al (100 nm)) exhibit maximum luminances (Lmax) of 82,057 and 78,385 cd m-2, maximum current efficiencies (ηc,max) of 68.28 and 44.95 cd A-1, resp., with low efficiency roll-off. In the experimental materials used by the author, we found (3-Bromophenyl)diphenylphosphine oxide(cas: 10212-04-1Name: (3-Bromophenyl)diphenylphosphine oxide)
(3-Bromophenyl)diphenylphosphine oxide(cas: 10212-04-1) belongs to mono-phosphine Ligands.Phosphine ligands are the most significant class of ligands for cross-coupling because of the alterability of their electronic and steric properties. Ligands play a key role in stabilizing and activating the central metal atom and are used in reactions, such as transition metal catalyzed cross-coupling.Name: (3-Bromophenyl)diphenylphosphine oxide
