2-(2-(Diphenylphosphoryl)phenyl)naphtho[2,3-d]oxazole (2-PPN), 2-(3-(diphenylphosphoryl)phenyl) naphtho[2,3-d]oxazole (3-PPN), and 2-(4-(diphenylphosphoryl)phenyl)naphtho[2,3-d]oxazole (4-PPN) were synthesized as new light-emitting materials based on the phosphine oxide-naphthoxazole structure. The one-pot synthesis of the phosphine-naphthoxazole compound was achieved using PPA as a solvent and as a catalyst for the cyclization reaction. The phosphine structure was oxidized to phosphine oxide using aq. H2O2, and the chemical structures were characterized via 1H-NMR, 13C-NMR, FT-IR, UV-Vis, elemental analysis (EA) and X-ray photoelectron spectroscopy (XPS). TGA under an N2 flow shows that the PPN derivatives were thermally stable at up to 400°C. The photoluminescence (PL) spectra of the PPN derivatives in chloroform exhibited maximum wavelengths at around 439 nm for 2-PPN, 447 nm for 3-PPN, and 436 nm for 4-PPN. Electroluminescence (EL) devices with different configurations (1-4) were fabricated via vacuum deposition, and devices 1-4 emitted greenish-blue light with a maximum emission at around 509 (2-PPN), 498 (2-PPN), 528 (3-PPN) and 501 (4-PPN) nm.
PHOSPHORYL DERIVATIVES WITH NEW STRUCTURES AND ORGANIC ELECTRONIC DEVICES USING THE SAME

Paragraph 0042-0044, (2016/11/28)
The present invention relates to phosphoryl derivatives with a novel structure and an organic electronic element using the same. A compound having oxazole, thiazole or pyrazole structures of the present invention increases light emitting efficiency due to the structures acting as a trap of electron or hole, where carbon-phosphorus bonding helps P=O transfer effectively energy by effectively blocking a communication between an aryl group and an electron withdrawing group (EWG). A compound of the present invention can be used not only as a light-emitting material in an organic electronic element but also as a hole-injection, hole-transport, electron-injection, electron-transport and a passivation (capping) material.
Radical phosphination of organic halides and alkyl imidazole-1- carbothioates
Sato, Akinori,Yorimitsu, Hideki,Oshima, Koichiro
, p. 4240 - 4241 (2007/10/03)
Taking advantage of a radical-based methodology, mild and chemoselective phosphination reactions of organic halide and alkyl imidazole-1-carbothioates have been developed. The mild reaction conditions allow labile functional groups to survive during the reaction. Copyright
Nickel-catalyzed reductive coupling of chlorodiphenylphosphine with aryl bromides into functionalized triarylphosphines
Le Gall, Erwan,Troupel, Michel,Nédélec, Jean-Yves
, p. 7497 - 7500 (2007/10/03)
Functionalized triarylphosphines are obtained with good yields in a one-step reaction of an equimolar mixture of chlorodiphenylphosphine and an aromatic bromide in NMP or DMF at 110°C in the presence of zinc dust and a catalytic amount of NiBr2
Electrosynthesis of triorganylphosphines from organic halides and chlorophosphines, catalyzed by nickel complexes
Budnikova,Kargin,Sinyashin
, p. 524 - 528 (2007/10/03)
The possibility of cross coupling of organic halides and chlorophosphines under the action of electrochemically generated Ni(0) complexes of 2,2′-bipy is shown. The final triorganylphosphines are formed by several pathways, including reaction of the σ complex of ArNiX with chlorophosphine and electron transfer-induced reductive elimination of Ph2PArNiX, leading to the cross-coupling product.
Nickel-catalysed electrochemical coupling between mono- or di-chlorophenylphosphines and aryl or heteroaryl halides
Budnikova, Yulia,Kargin, Yuri,Nedelec, Jean-Yves,Perichon, Jacques
, p. 63 - 66 (2007/10/03)
Nickel-catalysed electrochemical cross-coupling between aryl- or heteroaryl-halides and chlorodiphenylphosphine or dichlorophenylphosphine affords tertiary phosphines in good to high yields.
