Metallosilicate and Phosphosilicate Hybrid Materials Prepared by Non-Hydrolytic Sol-Gel Reactions
Original language description
We developed non-hydrolytic sol-gel routes to several families of metallosilicate and phosphosilicate hybrid inorganic-organic materials based on polycondensation reactions between acetoxysilanes 1RxSi(OC(O)CH3)4-x (1R = Me, Ph; n = 0-2), phosphoric andphosphonic acid trimethylsilylesters 2RP(O)(OSiMe3)2 (2R = OSiMe3, c-Hex, Ph), metal amides M(N3R2)n (M = Al, Ti; 3R = Me, Et; n = 3, 4) and metal alkoxides M(O4R)n (M = Al, Ti; 4R = i-Pr, t-Bu, SiMe3; n = 3, 4) in aprotic dry solvents. Alumosilicate xerogels were prepared by polycondensation reactions between Al(NMe2)3 or Al(Oi-Pr)3 and acetoxysilanes. These elimination reactions led to the formation of Si-O-Al networks and released dimethylacetamide or acetic acid ester and as byproducts, respectively. Titanosilicate xerogels were prepared by non-hydrolytic polycondensation reactions between Ti amides Ti(NR2)4 (R = Me, Et) or Ti alkoxides Ti(OR)4 (R = i-Pr, t-Bu, SiMe3) and acetoxysilanes.
