Control of micro/mesoporosity in non-hydrolytic hybrid silicophosphate xerogels
Original language description
Non-hydrolytic sol-gel reactions of acetoxysilanes with trimethylsilyl esters of phosphoric and phosphonic acids produce cross-linked matrices containing homogeneous dispersions of silicon and phosphoryl groups connected together by networks of Si-O-P(=O) linkages. These polycondensation reactions proceed cleanly and under mild conditions for a wide variety of precursor silanes RnSi(OAc)(4-n) (R = alkyl, aryl; n = 1, 2) and phosphoryl compounds RP(O)(OSiMe3)(2) (R = alkyl, aryl) to provide hybrid xerogels, the final properties of which are a sensitive function of the organic substituents and the Si : P ratio of the precursors. The reactions of bridged acetoxysilanes (AcO)(3)Si-X-Si(OAc)(3) and phosphoryl reagents (Me3SiO)(2)P(O)-X-P(O)(OSiMe3)(2) havealso been investigated and found to produce gels that exhibit large surface areas (up to 700 m(2) g(-1)).
