Abstract

Recent advances in preparation and application of hybrid organic‐silica monolithic capillary columns

“…Additionally, ring-opening polymerization has also been adopted to prepare the organic monoliths by using epoxycontained monomers and diamines [89,90]. More recently, we [91] utilized a POSS reagent of octaglycidyldimethylsilyl POSS (POSS-epoxy) (Fig. 6) as an epoxy monomer for preparation of a series of hybrid monoliths via ring-opening polymerization with diamines, such as 1,6-diaminohexane, 1,8-diaminooctane, 1,10-diaminodecane and 1,12-diaminododecane.…”

“…These are organic-inScheme 1. a) vinylPOSS (RSiO3 =2 ) n shown for n = 8, 10, 12; b) variety of thiol compounds explored in this study; the nomenclature attributed to the linker is identical to the respective polymer; and c) hybrid polymer 1 prepared with vinylPOSS and linker 1. organic hybrid, cage-like nanostructures (e.g., Scheme 1 a) that, in their chemical diversity, have already been used as building blocks for the generation of porous materials through thermolysis [5] and hydrosylation, [6] as well as other coupling reactions. [7] The preparation of monolithic porous materials involving POSS has often been addressed with amines, [8] and through uncontrolled, free-radical copolymerization with other monomers. [9] Recently, porous monolithic adsorbents prepared by simple free-radical polymerization of vinylPOSS have been reported.…”

Green Nanocomposites from Renewable Plant Oils and Polyhedral Oligomeric Silsesquioxanes

“…So far, a variety of functional POSS derivatives have been developed. Polymerizable POSS macromers, such as vinyl-functionalized POSS and oxirane-functionalized POSS, have been employed to copolymerize with organic monomers to afford a variety of polymer/POSS nanocomposites [15][16][17][18][19][20][21][22][23][24][25][26][27]. Polymerizable POSSs make a covalent attachment to a polymer matrix possible, and POSS units are well-dispersed in a polymer matrix.…”
