An Efficient Approach to Octabromophenylethyl‐Functionalized Cage Silsesquioxane and Its Use in Constructing Hybrid Porous Materials

Abstract

Octabromophenylethyl-functionalized silsesquioxane (BrPh-SQ) was synthesized by the Friedel-Crafts alkylation of octavinylsilsesquioxane (OVS) with bromobenzene, which acted as both the solvent and reactant and, furthermore, could be recycled after the reaction. The approach possesses the advantages of being mild, economic, and highly efficient. Further, BrPh-SQ was used as a building block in Heck reactions

Fluorine‐Containing Silsesquioxane‐Based Hybrid Porous Polymers Mediated by Bases and Their Use in Water Remediation

“…Thea dsorption isotherms for the FHPPs at 273 Ks how that the CO 2 uptake capacities for FHPP-1 and FHPP-2 are 3.24 wt %( 0.74 mmolg À1 )a nd 2.67 wt % (0.61 mmolg À1 ), respectively,a t2 73 Ka nd 1.07 bar.C ompared with FHPP-2,F HPP-1 possesses ah ighera dsorption capacity, due to its higher specific surface area and fluorine content. [35] The uptakes of CO 2 by the FHPPs are comparable to those of MOFs, [36] porous organic polymers (POPs), [37] and silsesquioxane-based porouspolymers [38,39] with similarsurface areas.…”

Effect of Octavinyl-Polyhedral Oligomeric Silsesquioxane on the Cross-linking, Cure Kinetics, and Adhesion Properties of Natural Rubber/Textile Cord Composites

“…They are distinguished from other common nanofillers such as organoclays, nanosilica, and nanotubes because if there is compatibility between the polymer and POSS nanoparticles, they can dissolve in the matrix. They are used for improving the mechanical, thermal, and flame retardancy properties of polymers by copolymerization, grafting, and blending. , Moreover, several multifunctional cage silsesquioxanes can be synthesized as mentioned in the literature. − …”

Modeling of Hydrogen Storage Utilizing Silsesquioxane Cages: Adsorption and Quasi-Dynamic Simulations of Encapsulation of H2 Molecule into Silsesquioxane Cages

“…In the present work, we study silsesquioxane (SQ) nanomaterial as a possible candidate for solid-state hydrogen storage. Silsesquioxane and its derivatives seem well suited for hydrogen storage and have attracted many experimental and theoretical researchers for gas adsorption and hydrogen storage ,,− because (1) they are light, stable, and porous; (2) several SQ compounds have been theoretically predicted for encapsulation using transition-state theory; and (3) they can be functionalized with organic and inorganic groups/particles and therefore have tunable properties. ,,,− …”
