“…chromatography, solid-phase extraction, etc. Also, these type of materials have been used as suitable supports in a diversity of heterogeneous catalysts for different organic reactions [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] . Indeed, the mesopore channels and high surface area of PMOs make them as an appropriate nanoreactor for releasing of the reactants into mesoporous channels and increases the reaction rate [30][31][32][33][34][35][36][37][38][39][40][41] .…”

in this study, preparation and characterization of a new magnetic propylsulfonic acid-anchored isocyanurate bridging periodic mesoporous organosilica (iron oxide@pMo-icS-prSo 3 H) is described. the iron oxide@pMo-icS-prSo 3 H nanomaterials were characterized by fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy and field emission scanning electron microscopy as well as thermogravimetric analysis, n 2 adsorption-desorption isotherms and vibrating sample magnetometer techniques. Indeed, the new obtained materials are the first example of the magnetic thermally stable isocyanurate-based mesoporous organosilica solid acid. furthermore, the catalytic activity of the iron oxide@pMo-icS-prSo 3 H nanomaterials, as a novel and highly efficient recoverable nanoreactor, was investigated for the sustainable heteroannulation synthesis of imidazopyrimidine derivatives through the Traube-Schwarz multicomponent reaction of 2-aminobenzoimidazole, c-H acids and diverse aromatic aldehydes. the advantages of this green protocol are low catalyst loading, high to quantitative yields, short reaction times and the catalyst recyclability for at least four consecutive runs. The use of heterogeneous catalysts has been developed because of their desirable properties and addressing many principles of green chemistry. Therefore, development and research in the heterogeneous catalysts has received major consideration due to disadvantages associated with homogeneous catalysts such as catalyst recovery, product separation, corrosion problems and environmental hazards 1-5. Along these lines, development of nanoporous materials with significant improved properties is a new and growing research field in the recent years 6-10. Highlyordered periodic mesoporous organosilicas (PMOs) materials, as a kind of inorganic-organic hybrid mesoporous materials, have attracted significant interest because of their noteworthy properties such as high surface area, narrow pore size distribution, adjustable mesopore diameter, high mechanical and hydrothermal stability, and highly tunable physicochemical properties by varying the nature and extent of the surface functionalization. PMOs which are mainly prepared from bridged organosilane precursors [(R′O) 3 SiR -Si(OR′) 3 ; R: organic bridging group, R′: methyl or ethyl] have found vast applications in various fields such as drug delivery systems, absorption and storage of mechanical energy, gas storage, electronics, sensors, luminescence, adsorbents,

“…In addition, the peak at 1634 cm −1 was possibly due to the stretching vibration of O−H bond from the Si‐OH or Zr‐OH groups on the surface of the catalysts. The peaks appearing at 3425, 918 as well as 810, and 526 cm −1 were attributed to the vibrations of O−H, Si‐−OH, and Si‐−O−Si bonds, respectively . Additionally, the other three IR absorption peaks appearing at 1384, 1156, and 1021 cm −1 originated from stretching vibrations of S−O, and S=O bonds from the ‐−SO 3 H group and/or SO 4 2− anion,,, which suggested that the ZrO 2 ‐PMO framework was successfully sulfonated by ClSO 3 H.…”

Ordered mesoporous sulfonic acid functionalized ZrO 2 /organosilica catalysts (SO 4 2À /ZrO 2 -PMO-SO 3 H) bearing tunable Brønsted, and Lewis acid site distributions were prepared by a P123directed sol-gel co-condensation route followed by ClSO 3 H functionalization. As-prepared catalysts were applied in the conversion of glucose to ethyl levulinate in ethanol medium. The SO 4 2À /ZrO 2 -PMO-SO 3 H-catalyzed target reaction followed a glucose-ethyl glucoside-ethyl fructoside-5-ethoxymethylfurfuralethyl levulinate pathway dominated by the synergistic effect of the super strong Brønsted acidity, and moderate Lewis acidity of the catalysts. Additionally, by combining the advantages of the considerably high Brønsted (696 meq g À1 ), Lewis acid site density (703 meq g À1 ), optimal Brønsted/Lewis molar ratio (0.99), and excellent porosity properties, the SO 4 2À /ZrO 2 -PMO-SO 3 H1.0 obtained at an initial Si/Zr molar ratio of 1.0 exhibited the highest ethyl levulinate yield (42.3 %) among the various tested catalysts. Moreover, the SO 4 2À /ZrO 2 -PMO-SO 3 H can be reused three times without obvious changes in activity, morphology, and chemical structure.[a] Dr.

“…The magnetic particle-based SPME improved the detection sensitivity of the catecholamine enantiomers by 10 folds. Two novel periodic mesoporous organosilica materials have also been used as the sorbents for the extraction of 7 chiral drugs [19]. The good cleanup effect led to fast CE separation with high resolution reaching 2.4~8.5.…”

Development of new capillary electrophoresis (CE) methodology and instrumentation, as well as application of CE to solve new problems, remains an active research area because of the attractive features of CE compared to other separation techniques. In this review, we focus on the representative works about sample preconcentration, separation media or capillary coating development, detector construction, and multidimensional separation in CE, which are judiciously selected from the papers published in 2018-2020.
