Synthesis and OLED characteristics of isomeric phosphine oxides containing naphthoxazole moiety

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.

Radical phosphination of organic halides and alkyl imidazole-1- carbothioates

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

Electrosynthesis of triorganylphosphines from organic halides and chlorophosphines, catalyzed by nickel complexes

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.
