What do we know about bifunctional cage-like T₈ silsesquioxanes? Theory versus lab routine

Abstract

The quest for ortho, meta, and para isomers, as a part of the enigmatic synthesis of bifunctional POSS, from theoretical and experimental standpoints, is unraveling in our paper.

Silsesquioxane Cages under Solvent Regimen: The Influence of the Solvent on the Hydrolysis and Condensation of Alkoxysilane

“…To Hence, the hypothesis regarding the selectivity of the corneropening process, which aimed to yield heterosubstituted POSSs, was disproven, 38 and is still under investigation. 39 Inferences can be drawn that the hydrolysis process occurs in a stochastic manner. Yet, intriguingly, a propensity toward the condensation of POSS(ONa) 3 and DDSQ(ONa) 4 systems emerges despite DDSQ(OH) 4 exhibiting superior stability in isopropanol.…”

“…Consequently, the hydrolysis of condensed octa -substituted POSSs culminates, and the subsequent phase involves self-assembling “open” cages through condensation. Hence, the hypothesis regarding the selectivity of the corner-opening process, which aimed to yield heterosubstituted POSSs, was disproven, and is still under investigation …”
