3-Mercaptopropyl functionalized SBA-15 (SH-SBA) and 3-mercaptopropyl functionalized ethenylene bridged periodic mesoporous organosilica (SH-PMO) were included in a Diffusive Gradients in Thin film (DGT) probe and compared to similar commercially available resins also containing thiol functional groups, such as Sumichelate Q10R (SQR) and 3-mercaptopropyl functionalized silica gel (SH-KG), and al...

Amino-functionalized SBA-15 type mesoporous silicas having unique hexagonal platelet morphologies with short channels (100-300 nm) running parallel to the thickness of the nanostructured hexagonal platelet type morphologies have been directly synthesized by co-condensation of aminopropyltriethoxysilane (APTES) and sodium metasilicate as a silica source in the presence of Pluronic P123 triblock ...

Mesoporous SBA-15 functionalized with aggregation-induced emission (AIE) luminogens serves as an efficient and recyclable fluorescent sensor for the detection of picric acid (PA), with a quenching constant of up to 2.5 × 10(5) M(-1) in a water solution, presenting a new model for the supersensitive detection of explosives.

Surface functionalization of SBA-15 followed by its reaction with Cu(OAc)(2) has been carried out to develop a new Cu-grafted functionalized mesoporous material, which catalyzes one-pot three component coupling of different aryl halides with thiourea and benzyl bromide in aqueous medium to produce aryl thioethers in very good yields (80-88%).

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...

Two hybrid materials based on mesoporous silicas SBA-15 and MCM-41 functionalized with stable and electrically neutral Gd(iii) macrocyclic complexes were prepared, and their (1)H NMR relaxometric properties investigated as a function of temperature and magnetic field strength.

sulfonic acid functionalized sba-15 as a nanoporous acid catalyst was used in the synthesis of 2-aryl benzoxazoles 4 by the condensation of 2-aminophenol 1 and benzoyl chlorides 2 under microwave irradiation in solvent free reaction conditions. the advantages of this methodology are good product yields (60-98%), being environmentally benign, short reaction times and easy work up.

SBA-15 grafted with N-(4-(trimethylsilyl) butyl)-9H-fluorene-9-amine was synthesized by a simplestrategy and applied to removal of Acid Red 33 and Acid Black 194 from aqueous solutions. SBA-15 was synthesized and Functionalized according to procedure in the literature. Fluorenefunctionalized SBA-15 was showed the BET surface area 200 m2g-1 and pore diameter 4.2 nm,based on adsorption-desorption...

A recoverable Rh/N-SBA-15 heterogeneous catalyst for asymmetric hydroformylation of styrene was prepared by post grafting method. XRD, TG, 29 Si MAS NMR and ICP characterization, revealed that the introduction amino silane RhCl 3 had no adverse influence on ordered mesoporous structure support. The proved to be highly efficacious stable styrene. experimental results demonstrated improved loadin...
