Many medical and chemical applications require target molecules to be delivered in a controlled manner at precise locations. Metal–organic frameworks (MOFs) have high porosity, large surface area, tunable functionality are promising carriers for such purposes. Current approaches incorporating based on multistep postfunctionalization. Here, we report novel approach that combines MOF synthesis molecule encapsulation one-pot process. We demonstrate drug dye can encapsulated zeolitic imidazolate...
A series of highly porous isoreticular lanthanide-based metal–organic frameworks (LnMOFs) denoted as SUMOF-7I to SUMOF-7IV (SU = Stockholm University; Ln La, Ce, Pr, Nd, Sm, Eu, and Gd) have been synthesized using tritopic carboxylates the organic linkers. The SUMOF-7 materials display one-dimensional pseudohexagonal channels with pore diameter gradually enlarged from 8.4 23.9 Å, a result increasing sizes structures solved by single crystal X-ray diffraction or rotation electron (RED)...
Porous NOTT-202a shows exceptionally high uptake of SO2, 13.6 mmol g(-1) (87.0 wt %) at 268 K and 1.0 bar, representing the highest value reported to date for a framework material. undergoes distinct irreversible phase transition upon SO2 268-283 give NOTT-202b which has enhanced stability due formation strong π···π interactions between interpenetrated networks.
Polysubstituted 5- and 6-membered carbocycles were synthesized by the title reaction. The one-pot dynamic relay process generates four new stereocenters, including a quaternary carbon center, in highly enantioselective fashion (99.5:0.5→99:0.5 e.r.) using simple combination of palladium chiral amine co-catalysts.
The "escape-by-crafty-scheme" strategy is an efficient approach to prepare metal-oxide nanomaterials with desirable morphology and crystal planes inherited from coordination-polymer nanoparticle precursors, which can be designed finely tuned by soft chemical assembly of metal ions organic ligands at the molecular level (see scheme; ptcda=perylene-3,4,9,10-tetracarboxylic dianhydride). Detailed facts importance specialist readers are published as "Supporting Information". Such documents...
The highly enantioselective (up to >99.5:0.5 er) synthesis of polysubstituted spirocyclic oxindoles with four new contiguous stereocenters, including the spiro all-carbon quaternary center, is disclosed. It accomplished by stereoselective control a dynamic conjugate/intramolecular allylic alkylation relay sequence based on synergistic cooperation metal and chiral amine catalysts in which careful selection organic ligand, complex, essential. intramolecular C–C bond-forming step occurred only...
A novel method for rapid preparation of Bi2Te3 nano-sized powders with an average particle size about 70 nm was developed. starting powder mixture consisting coarse particles ∼5 mm ground using cryogenic grinding in the liquid nitrogen. For comparison, conventional high-energy ball milling used to prepare powders. Sintering properties as-prepared investigated by spark plasma sintering (SPS). The effects procedure on crystallinity, morphology and structure were examined X-ray diffraction...
Polysubstituierte fünf- und sechsgliedrige Carbocyclen wurden mit der Titelreaktion erhalten. Der dynamische Eintopf-Staffelprozess erzeugt einer einfachen Katalysatorkombination aus Palladium einem chiralen Amin hoch enantioselektiv (99.5:0.5→99:0.5 e.r.) vier neue Stereozentren, darunter ein quartäres Kohlenstoffzentrum.
