Description
| - Non-hydrolytic sol-gel reactions are viable alternatives to classical aqueous techniques in the area of synthesis of multimetallic oxides and inorganic-organic hybrid materials in the form of xerogels, nanoparticles, and thin films. We developed a non-hydrolytic sol-gel route based on acetic acid ester elimination providing silicophosphate hybrid inorganic-organic materials. The polycondensation reactions between Si(OAc)4 and OP(OSiMe3)3 lead to microporous xerogels with surface areas up to 568 m2 g-1. The structure of xerogels was built up exclusively from Si-O-P bonds and contained octahedrally coordinated silicon atoms, which are characteristic for crystalline silicon phosphates.1 We changed starting precursors to acetoxysilanes and phosphonic acid esters with bridging alkyl or aryl groups (AcO)3Si-(CH2)x-Si(OAc)3 (x = 1-3, 6), (Me3SiO)2P(O)-3R-P(O)(OSiMe3)2 (3R = C2H4, C6H4).
