A novel SBA-15-functionalized TEMPO confined ionic liquid [BMIm]Br was found to be a highly efficient and recyclable catalyst system for the transition-metal-free aerobic oxidation of a wide range of structurally diverse alcohols. Thanks to the strong physical confinement of the ionic liquid inside the mesochannels of SBA-15-supported TEMPO, the resulting solid catalyst showed improved selectiv...

the surface of sba-15 was modified by diphenylphosphine; then, it was treated with butane sultone and sulfuric acid to obtain brønsted acid ho3s-phosphonium based ionic liquid functionalized sba-15 with hso4- as a counteranion. it efficiently catalyzed synthesis of pyrano[3,2-c]chromenone derivatives through the reaction of 4-hydroxycoumarin and chalcones at 60 °c in water/ethanol. good yields,...

A kind of mesoporous hybrid luminescence material was assembled through the ion exchange method between [Ln(DPA)3](3-) and ionic liquid functionalized SBA-15. [Ln(DPA)3](3-) was successfully anchored onto positive-charge modified SBA-15 by the strong electrostatic interaction. In [Ln(DPA)3](3-), Ln(3+) ions are in 9-fold coordination through six oxygen atoms of carboxyl groups and three nitroge...

N-Methyl-Nʹ-propyltrimethoxysillylimidazolium chloride was prepared as ionic liquid (IL) containing silylating agent and then used for modification of the internal surface of SBA-15 to gain a heterogeneous ionic liquid catalyst. Subsequently, the obtained SBA-IL was characterized using various techniques, including SEM and TEM images, FT-IR, X-ray diffraction, TGA/DTA and BET ...
