Microwave-assisted synthesis of cyclopentyltrisilanol (c-C5H9)7Si7O9(OH)3

Nanohybrid polyurethane/functionalized silsesquioxane systems. Part I. Structural investigations using FT-IR and NMR methods

“…Wtedy, gdy rozmiary cz¹stek fazy nieorganicznej nie przekraczaj¹ 100 nm, u¿ywane jest okreoelenie mate-ria³y nanohybrydowe [9][10][11][12][13][14][15][16][17]. Jedn¹ z grup takich mate-ria³ów stanowi¹ uk³ady, w których ró¿nego rodzaju klastery lub cz¹stki nieorganiczne s¹ zwi¹zane kowalencyjnie z polimerami organicznymi [18][19][20][21][22][23][24]. Bardzo intere-suj¹cym przyk³adem uk³adów nanohybrydowych s¹ poliuretany zawieraj¹ce wbudowane chemicznie cz¹steczki poliedrycznych silseskwioksanów (POSS).…”

Modification of cellulose with reactive polyhedral oligomeric silsesquioxane and nano-crosslinking effect on color properties of dyed cellulose materials

“…Reactive polyhedral oligomeric silsesquioxane containing multi-N-methylol (R-POSS) is one of POSS derivatives as candidates to modify cellulose. It is attractive staring monomer and has corner-capping framework of condensed POSS trisilanols (Feher, Soulivong, & Eklund, 1998;Feher & Wyndham, 1998;Janowski & Pielichowski, 2008;Xie, Zhang, & Yu, 2009). …”

Synthesis and characterization of reactive polyhedral oligomeric silsesquioxanes (R-POSS) containing multi-N-methylol groups

“…Some families of POSS monomers with different organic groups have been developed as precursors to hybrid inorganic-organic polymers. Previous studies have revealed that functional POSS monomers can generally be obtained by the controlled cleavage of completely condensed polyhedral oligosilsesquioxane in the presence of strong acid or base [20][21][22]. Corner-capping of the POSS trisilanol can be carried out using a variety of couple reagent.…”
