Abstract
Disclosed are a protected alcohol or derivative thereof, a surface-modified organic-inorganic hybrid glass, and preparation methods thereof. More specifically, disclosed are a protected alcohol or derivative thereof and a surface-modified organic-inorganic hybrid glass, which are prepared by allowing a silane compound, having vinyl or a vinyl derivative, to react with an alcohol or derivative thereof or with an organic-inorganic hybrid glass, in the presence of an acid catalyst, a transition metal catalyst and an organic solvent, so as to introduce an organic group thereto even at room temperature, as well as preparation methods thereof. The disclosed invention allows a functional group to be effectively introduced into alcohol or a derivative thereof or into an organic-inorganic hybrid glass, not only high temperatures but also room temperature, and thus is highly effective in introducing compounds having a thermally sensitive functional group, for example, natural compounds or proteins. Also, the invention makes it possible to introduce various organic groups and to separate and purify organic macromolecule-bonded organosilane compounds using a silica gel column so as to effectiv…
