Mesoporous hybrid inorganic-organic phosphosilicates by non-hydrolytic sol-gel reactions
Original language description
Non-hydrolytic sol-gel reactions based on condensation of two functional groups are studied as an alternative to aqueous techniques for the 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 parent phosphosilicate and its hybrid inorganic-organic derivatives. The polycondensation reactions between Si(OAc)4 and OP(OSiMe3)3 provides microporous phosphosilicate xerogels with surface areas up to 570 m2 g-1. Substitution reactions of residual acetoxy and trimethylsiloxy groups on the surface with a variety of reagents, such as SiCl4, RSiCl3, POCl3, AlX3, ROH, and Me3SiOSiMe3, show versatility of the synthesized phosphosilicate xerogels in tuning their properties, such as Bronsted and Lewis acidity.
