Silicon-containing substituted metal complex

The invention discloses a silicon-containing substituted metal complex. The novel silicon-containing substituted metal complex has a general formula of M (La) m (Lb) n (Lc) q, and the ligand La is a ligand with silicon group substitution and can be used as a luminescent material in an electroluminescent device. The novel metal complexes have the advantages of remarkably improving the quantum efficiency of the material, effectively controlling the light-emitting wavelength and the light-emitting color and reducing the driving voltage, and can provide better device performance. The invention also discloses an electroluminescent device and a compound formulation.

Continuous-flow Si-H functionalizations of hydrosilanesviasequential organolithium reactions catalyzed by potassiumtert-butoxide

We herein report an atom-economic flow approach to the selective and sequential mono-, di-, and tri-functionalizations of unactivated hydrosilanesviaserial organolithium reactions catalyzed by earth-abundant metal compounds. Based on the screening of various additives, we found that catalytic potassiumtert-butoxide (t-BuOK) facilitates the rapid reaction of organolithiums with hydrosilanes. Using a flow microreactor system, various organolithiums bearing functional groups were efficiently generatedin situunder mild conditions and consecutively reacted with hydrosilanes in the presence oft-BuOK within 1 min. We also successfully conducted the di-funtionalizations of dihydrosilane by sequential organolithium reactions, extending to a gram-scale-synthesis. Finally, the combinatorial functionalizations of trihydrosilane were achieved to give every conceivable combination of tetrasubstituted organosilane libraries based on a precise reaction control using an integrated one-flow system.

Effect of silylated triarylphosphine ligands on rhodium-catalyzed hydrosilylation

A series of silylated triarylphosphines was synthesized. Hydrosilylation reactions of styrene with triethoxysilane catalyzed by RhCl3/silylated triarylphosphine complexes were investigated. The complexes RhCl3/phenylbis(4-trimethylsilylphenyl)phosphine and RhCl3/tris(4-trimethylsilylphenyl)phosphine exhibited higher activity as well as greater β-adduct selectivity, and no unsaturated product was obtained. The results suggest that the silyl moieties have a significant impact on the catalytic process. Copyright

Transmission of electronic effects via a SiMe2 spacer in 4-mono- and 4,4'-disubstituted diphenyldimethylsilanes: 29Si and 13C NMR spectroscopy and PM3 semi-empirical calculations

Some 29Si and 13C NMR studies were performed of series of 4-substituted phenyltrimethylsilanes and 4-substituted and 4,4'-disubstituted diphenyldimethylsilanes.Within each series linear relationships are found between the chemical shifts and (a) the Hammett substituent constants ?p and (b) the PM3-calculated total atomic charges.It is inferred that the SiMe2 ?-type spacer weakly mediates substituent effects in the ground state via a bond polarization mechanism.A comparison with available data for 4-substituted and 4,4'-disubstituted diphenylmethanes shows that the SiMe2 group is a better transmitter of electronic effects that the CH2 group.
