Photonic structuring improves colour purity of rare-earth nanophosphors

May 26, 2018 | 2018, 2018, 2018, 2018

Nanophosphor integration in an optical cavity allows unprecedented control over both the chromaticity and the directionality of the emitted light, without modifying the chemical composition of the emitters or compromising their efficiency. Our approach opens a route...

Isolation of a Cationic Platinum(II) s-Silane Complex

Abr 26, 2018 | Sin categoría

The platinum complex [Pt(ItBuiPr′)(ItBuiPr)][BArF] interacts with tertiary silanes to form stable (<0 °C) mononuclear PtII σ‐SiH complexes [Pt(ItBuiPr′)(ItBuiPr)(η1‐HSiR3)][BArF]. These compounds have been fully characterized, including X‐ray diffraction methods,...

Epimerization of glucose over ionic liquid/ phosphomolybdate hybrids: structure-activity relationship

Mar 26, 2018 | Sin categoría

The influence of the crystal structure and chemical nature of some ionic liquid/phosphomolybdate hybrids on their catalytic activity in the epimerization of glucose was studied. A clear evidence of structure–activity relationship was found. The inorganic part of the...

Selective catalytic synthesis of amino-silanesat part-per million catalyst loadings

Feb 26, 2018 | Sin categoría

Platinum(II) complex [Pt(ItBu0)(ItBu)][BArF4] (1a) is a highly active and selective catalyst in the dehydrocoupling of amines and silanes at part-per-million catalyst loadings (up to 10 ppm, 0.001 mol%), achieving the highest TON and TOF numbers reported in the...

Broad Scope Synthesis of Ester Precursors of Nonfunctionalized Chiral Alcohols Based on the Asymmetric Hydrogenation of α,β- Dialkyl-, α,β- Diaryl-, and α-Alkyl-β-aryl-vinyl Esters

Dic 26, 2017 | Sin categoría

The catalytic asymmetric hydrogenation of trisubstituted enol esters using Rh catalysts bearing chiral phosphinephosphite ligands (P-OP) has been studied. Substrates covered comprise α,β-dialkyl, α-alkyl-β-aryl, and α,β-diarylvinyl esters, the corresponding...

Glycodendrimers as chondroitin sulfate mimetics: synthesis and binding to growth factor midkine
