¹³C‐ENDOR Investigation of an Organic Tetraradical in the Quintet State; Synthesis of a Fourfold ¹³C‐Labeled Tetrakisgalvinol

Abstract

elution with 5 mM sodium phosphate buffer on a phosphate-containing Dowex 1-X2 column. The free trisaccharide 3, whose interglycosidic linkages were confirmed by i H-NMR spectroscopy,"] was thereby obtained directly on a 50-pmol scale (yield: 31 mg, 52%).

Design, preparation and application of conjugated microporous polymers

“…Through Fourier transform infrared (FTIR) spectroscopy and elemental analysis, they found that the monomers were almost completely converted to polymers under reaction conditions of 400 °C and 40 h . A novel three‐dimensional porous aromatic framework based on tetrakis(4‐cyanophenyl)methane building unit and a triangular triazine ring was designed and produced, showing selective sorption of benzene, thermal stability and a Langmuir surface area of 1109 m 2 g −1 . Wang and co‐workers reported ultra‐microporous polymers based on one of the most common thermosetting networks, cyanate ester resins, in facile cyano cyclotrimerization .…”

Facile synthesis of hierarchical triazine-based porous carbons for hydrogen storage

“…Anhydrous zinc chloride was further dried at 120 C in vacuo overnight prior to use. Tetra(4-bromophenyl)methane [15] and tetra(4-bromophenyl)ethene [16] were synthesized according to reported procedures.…”

A Porous Aromatic Framework Functionalized with Nitro Groups and Its Carbon Dioxide Adsorption

“…BPM (127 mg, 0.2 mmol) and PBPM (246 mg, 0.15 mmol), which were prepared following literature methods (Supporting Information), 13,14 were dissolved in anhydrous DMF (10 mL) under an argon atmosphere. Cesium carbonate (326 mg, 1.0 mmol), tetrakis(triphenylphosphine)palladium(0) (23.0 mg, 0.02 mmol), water (2.0 mL), and ethanol (2.0 mL) were added to the solution subsequently.…”
