A surface-modified inorganic material and a preparation method thereof. A surface-modified inorganic material is provided which is obtained by allowing an organosilane compound having allyl or an allyl derivative to react with an inorganic material, particularly solid silica or ITO glass, in the presence of an acid and an organic solvent, to introduce an organic group into the inorganic material even at room temperature, as well as a preparation method thereof. The invention can effectively introduce the organic group into the inorganic material even at room temperature, and thus is very effective in introducing compounds having a thermally sensitive functional group, for example, natural compounds or proteins. It is possible to introduce various organic groups into an inorganic material and to separate and purify organic molecule-bonded organosilane compounds using a silica gel column to effectively bond them to inorganic materials. Accordingly, the invention is very useful in the chemical industry.
一种表面改性的无机材料及其制备方法。提供了一种表面改性的无机材料,通过在酸和有机溶剂存在下,使具有烯丙基或烯丙基衍生物的有机硅烷化合物与无机材料,特别是固体二氧化硅或ITO玻璃反应,将有机基引入无机材料,即使在室温下也能实现,并提供了其制备方法。该发明可以有效地在室温下将有机基引入无机材料,因此在引入具有热敏感功能基团的化合物,例如天然化合物或蛋白质时非常有效。可以将各种有机基引入无机材料,并使用硅胶柱分离和纯化有机分子结合的有机硅烷化合物,有效地将它们与无机材料结合。因此,该发明在化工行业中非常有用。
