A Facile Route to Difunctionalized Monosubstituted Octasilsesquioxanes

Abstract

A series of difunctionalized monosubstituted octasilsesquioxanes have been synthesized that bear ester, amino acid, alcohol, haloalkyl, or azido functional groups. These units are suitable nanobuilding blocks for the preparation of new organic-inorganic hybrid materials.

Triphenylamine‐Functionalized Silsesquioxane‐Based Hybrid Porous Polymers: Tunable Porosity and Luminescence for Multianalyte Detection

“…Octavinylsilsesquioxane (OVS) is a versatile precursor, and has been explored extensively as a potential starting material for nanohybrid synthesis because it is rigid, highly functional, and exceptionally robust with respect to heat and water . OVS has also been used to prepare hybrid porous polymers through various methods such as free radical polymerization, the Heck reaction, and the Friedel–Crafts reaction .…”

“…[22][23][24][25][26][27][28][29] Recently, many hybrid porous polymers were prepared via the topology combination from cubic OVS with planar molecules, 30 tetrahedral molecules, 31,32 cubic molecules [33][34][35][36] and polymer.

Highly untangled multiwalled carbon nanotube@polyhedral oligomeric silsesquioxane ionic hybrids: Synthesis, characterization and nonlinear optical properties

“…To this aim, chloropropylisobutyl POSS â was treated with sodium iodide to gain iodopropylhepta(isobutyl)POSS (POSS-I) [35]. Then, mono-imi-POSS/I has been obtained as a white solid in high yield, via alkylation of 1-vinylimidazole by POSS-I [40].…”

“…The synthesis was performed following the procedure reported in the literature [35]. 10 g of sodium iodide (67 mmol) were added to a solution of chloropropylisobutyl POSS â (1 g, 1.11 mmol) in THF (25 mL) and acetone (10 mL) under N 2 atmosphere.…”
