Phenylene-bridged hybrid silica spheres for high performance liquid chromatography†
Highly monodisperse 1,3-phenylene-bridged hybrid organosilica spheres (m-PHS) were synthesized by co-condensation of tetraethoxysilane (TEOS) and 1,3-bis(triethoxysilyl)benzene (1,3-BTEB) using dodecylamine (DDA) and cetyltrimethylammonium bromide (CTAB) as templates. In this method, three important factors are the surfactants, the ethanol–water volume ratio and the TEOS/1,3-BTEB molar ratio. T...

متن کاملHeterotrimetallic complexes of a phenylene-bridged tricarbene ligand.
Reaction of the benzene-1,3,5-trisimidazolium salt H3-1(Br)3 with [Rh(Cp*)(Cl)2]2 results in the formation of the dinuclear, doubly orthometalated complex [2]Br, which yields, depending on the metal source provided, either a triply orthometalated heterotrimetallic Rh2/Ir complex [3] or trinuclear heterotrimetallic Rh2/Au complexes of types [4a] or [4b].
متن کاملo-Phenylene-bridged Cp/sulfonamido titanium complexes for ethylene/1-octene copolymerization.
The Suzuki-coupling reaction of 2-(dihydroxyboryl)-3,4-dimethyl-2-cyclopenten-1-one and 2-(dihydroxyboryl)-3-methyl-2-cyclopenten-1-one with 2-bromoaniline derivatives affords cyclopentenone compounds from which cyclopentadiene compounds, 4,6-R'(2)-2-(2,5-Me2C5H3)C6H2NH2 and 4,6-R'(2)-2-(2,3,5-Me3C5H2)C6H2NH2 are prepared. After sulfonation of the -NH2 group with p-TsCl, metallation is carried ...
متن کاملOligomeric polymer surfactant driven self-assembly of phenylene-bridged mesoporous materials and their physicochemical properties.
The detailed synthesis of highly hydrophobic average pore benzene-bridged hybrid mesoporous silicas under an acidic medium is described. With the use of a 1,4-bis(triethoxysilane)benzene silsesquioxane precursor and biodegradable alkyl polyoxyethylene (Brij-56 or Brij-76) nonionic surfactant oligomers as supramolecular templates, no molecular scale periodicity was observed. The well-defined mes...
