Preparation of POSS-based organic–inorganic hybrid mesoporous materials networks through Schiff base chemistry

Construction of Hybrid Porous Materials from Cubic Octavinylsilsesquioxane through Friedel–Crafts Reaction Using Tetraphenylsilane as a Concentrative Crosslinker

“…[10][11][12] Some micro-mesoporous polymers from POSS-based precursors have been prepared through various methods including hydrosilylation, [13] Sonogashira coupling reaction, [6,7] Yamamoto coupling reaction, [8] Heck [9] and Friedel-Crafts reaction, [14] radical polymerization, [15,16] and others. [17][18][19] The use of rigid or stereocontorted monomers as building blocks, especially tetrahedral monomers, is an efficient means by which to design porous polymers with large specific surface areas. [20][21][22][23][24][25][26] Common tetrahedral monomers mainly include carbon-centered and silicon-centered compounds.…”

Synthesis of eugenol-based polybenzoxazine-POSS nanocomposites for low dielectric applications

“…Hybrid materials containing both inorganic and organic components are expected to have increased performance capabilities relative to their nonhybrid materials , because of their compatibility . Silsesquioxanes are compounds with general formula (RSiO 1.5 ) n , where “R” is an organic group or hydrogen and can have various geometrical structural orders, including random, ladder and cage structures; the latter are known as POSS .…”

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

“…Thus, cage polymer 1 shows excellent thermal stability and is more stable than some other SQ-based porous polymers. [15,28,48] The capture and storage of carbon dioxide are potential applications, and the fantastic field of porous materials, especially CO 2 concentration, has increased rapidly in recent years. [49] To evaluate the performance of cage polymer 1 in CO 2 storage, the physisorption isotherm of CO 2 was measured at 273 K. As shown in Figure 10, the CO 2 uptake of the network polymer increases with absolute pressure.…”

“…[27] The resulting hybrid porous materials exhibited high specific surface areas and exceptional hydrogen uptake. Besides, many other traditional organic reactions have been applied to prepare SQ-based hybrid porous polymers, such as the Friedel-Crafts reaction, [15] thermolysis, [16b] Schiff base chemistry, [28] and in situ homocoupling reaction. [29] Especially, Heck coupling has become an important method to exploit SQ-based porous materials.…”
