Kim, Jin-Hyoung; Kim, So-Yoen; Jang, Seol; Yi, Seungjun; Cho, Dae Won; Son, Ho-Jin; Kang, Sang Ook published the artcile< Blue Phosphorescence with High Quantum Efficiency Engaging the Trifluoromethylsulfonyl Group to Iridium Phenylpyridine Complexes>, Electric Literature of 2252-45-1, the main research area is iridium trifluoromethylsulfonylphenylpyridine complex synthesis crystal mol structure blue phosphorescence; cyclic voltammetry iridium trifluoromethylsulfonylphenylpyridine complex.

Incorporation of an electron-withdrawing – SO2CF3 substituent to cyclometalating CN̂-phenylpyridine (ppy) ligand resulted in an expected blue-shifted phosphorescence in the corresponding homoleptic Ir(ppySCF3)3 complex, showing the emission of λem = 464 nm at 300 K. One of its heteroleptic derivatives, modified by a pyrazolyl borate LX ligand, Ir(ppySCF3)2(bor), exhibited further blue-shifted phosphorescence of λem = 460 nm at 300 K. Cyclic voltammograms (CVs) and d.-functional theory (DFT) calculations supported the efficacy of the electron-withdrawing capability of the SO2CF3 substituent lowering HOMO energy, and obtained widened bandgaps and resumed blue emissions for all of the Ir complexes studied. The homoleptic complexes of both substituents, Ir(ppySCF3)3 and Ir(ppySF)3, reached the higher quantum yields (ΦPL) of (0.89 and 0.72), resp. Similarly, emission quantum yields (ΦPL) of the heteroleptic derivatives were reported to be (0.75, 0.83, and 0.87) for Ir(ppySCF3)2(acac), Ir(ppySCF3)2(bor), and Ir(ppySCF3)2(pic), resp. Emission kinetics support the enhanced quantum efficiency when kr and knr values are compared between Ir(ppySCF3)3 and Ir(ppySF)3, and both values favorably contribute to attaining a higher quantum efficiency for Ir(ppySCF3)3. Among solution-processed multilayered devices having an ITO/PEDOT:PSS/TCTA:Ir dopant (10:1, weight/weight)/TmPyPB/Liq/Al structure, a heteroleptic dopant, Ir(ppySCF3)2(bor), exhibited better device performance, reporting an external quantum efficiency (EQE) of 1.14%, current efficiency (CE) of 2.31 cd A-1, and power efficiency (PE) of 1.21 lm W1-, together with blue chromaticity of CIEx,y = (0.16, 0.32). Blue phosphorescence of Ir(III) complexes can be tuned with the introducing of strong electron withdrawing substituents and the variation in the ancillary ligands. Crystallog. data are given.

A visible-light-driven protocol for the synthesis of aryl trifluoromethyl thioethers under photocatalyst- and metal-free conditions has been pursued. The procedure exploits the peculiar properties of arylazo sulfones (having electron-rich or electron-poor substituents on the (hetero)aromatic ring) as photochem. precursors of aryl radicals and S-trifluoromethyl arylsulfonothioates as easy-to-handle trifluoromethylthiolating agents.

Luo, Ziwei; Yang, Xinkan; Tsui, Gavin Chit published the artcile< Perfluoroalkylation of Thiosulfonates: Synthesis of Perfluoroalkyl Sulfides>, Formula: C7H4BrF3S, the main research area is perfluoroalkyl sulfide synthesis perfluoroalkylation thiosulfonate.

A practical synthesis of perfluoroalkyl sulfides is described. The method employs stable and readily accessible thiosulfonates as new electrophiles with com. nucleophilic perfluoroalkylating reagents. The mild reaction conditions allow access to a wide variety of both aryl- and alkyl-substituted perfluoroalkyl sulfides amenable to pharmaceutical development. Furthermore, the reaction operation is straightforward, odorless, does not produce toxic wastes, and, therefore should appeal to practitioners in industrial-scale productions.

For color-pure phosphorescence organic light emitting diodes (PHOLEDs), we synthesized the trifluoromethyl sulfonyl substituted ligand and two new blue Iridium complexes with perfluoro-sulfonyl group (SOCF3pic and SOCF3mpic). The both iridium complexes showed similar photophys. and thermal properties while the HOMO energy leves of two Iridium complexes slightly differnet to be -5.84 eV for SOCF3pic and -5.74 eV for SOCF3mpic, resp. The device with the SOCF3mpic dopant exhibited higher device efficiencies of 7.17 cd/A and 3.7% compared to that with the SOCF3pic dopant (4.03 cd/A and 2.78%). Two-dimensional GIXD images of scattered X-ray intensity from surface to full depth for SOCF3pic-doped and SOCF3mpic-doped TCTA:4PTPS films were characterized for preferential orientation along the out-of-plane direction.

Friis, Stig D.; Pirnot, Michael T.; Dupuis, Lauren N.; Buchwald, Stephen L. published the artcile< A Dual Palladium and Copper Hydride Catalyzed Approach for Alkyl-Aryl Cross-Coupling of Aryl Halides and Olefins>, Recommanded Product: (3-Bromophenyl)(trifluoromethyl)sulfane, the main research area is palladium copper hydride catalyzed cross coupling aryl halide olefin; alkenes; copper; cross-coupling; homogeneous catalysis; palladium.

We report an efficient means of sp2-sp3 cross coupling for a variety of terminal monosubstituted olefins with aryl electrophiles using Pd and CuH catalysis [e.g., 4-bromoanisole + 4-phenyl-1-butene → MeOC6H4-4-(CH2)4Ph in presence of [Pd(cinnamyl)Cl]2, BrettPhos, CuCl.(R)-DTBM-SEGPHOS and Me2PhSiH]. In addition to its applicability to a range of aryl bromide substrates, this process was also suitable for electron-deficient aryl chlorides, furnishing higher yields than the corresponding aryl bromides in these cases. The optimized protocol does not require the use of a glove-box and employs air-stable Cu and Pd complexes as precatalysts. A reaction on 10 mmol scale further highlighted the practical utility of this protocol. Employing a similar protocol, a series of cyclic alkenes were also examined Cyclopentene was shown to undergo efficient coupling under these conditions. Lastly, deuterium-labeling studies indicate that deuterium scrambling does not take place in this sp2-sp3 cross coupling, implying that β-hydride elimination is not a significant process in this transformation.

Wu, Wei; Wang, Biyun; Ji, Xinfei; Cao, Song published the artcile< Direct copper-catalyzed oxidative trifluoromethylthiolation of aryl boronic acids with AgSCF3>, Application of C7H4BrF3S, the main research area is arylboronic acid silver trifluoromethylthiolate copper catalyst trifluoromethylthiolation; aryl trifluoromethyl thioether preparation.

A copper-catalyzed direct oxidative trifluoromethylthiolation of aryl boronic acids with AgSCF3 was developed. This approach provided straightforward and efficient access to a variety of aryl trifluoromethyl sulfides from an easily prepared and stable nucleophilic trifluoromethylthiolation reagent AgSCF3, and readily available nucleophilic arylboronic acids, thus avoiding the preparation of electrophilic trifluoromethylthiolating reagents in advance. Preliminary mechanistic experiments indicated that AgSCF3 served as both a source of SCF3 and an oxidant.
