The sol–gel process involving hydrolysis and condensation reactions is an attractive way to form siloxane based hybrid materials since it is a one-step method performed under mild conditions. Organic–inorganic hybrids having a talc-like structure (TLH) can be obtained using this procedure starting from organotrialkoxysilanes having the formula R–Si(OR′)₃ (where R stands for an organic moiety and R′ for a methyl or ethyl group) with different functionalities, an aqueous or ethanolic solution of a magnesium salt, and in some cases, an aqueous solution of sodium hydroxide. In this way, the organic chains are covalently bonded to the silicon of the tetrahedral sheets, pointing toward the interlayer space. The interesting feature in this case is that as many organotrialkoxysilanes are on the market, a wide range of organic moieties can be introduced in the interlayer space leading to applications in various fields. This review highlights the latest trends and the multifaceted applications of these functional layered compounds.

具有滑石样结构的有机-无机杂种作为合适的宿主，可以招待各种各样的物种

涉及水解和缩合反应的溶胶-凝胶工艺是形成硅氧烷基杂化材料的一种有吸引力的方法，因为它是在温和条件下执行的一步法。可以使用此程序从具有式R–Si（OR'）_3的有机三烷氧基硅烷开始获得具有滑石样结构（TLH）的有机-无机杂化体（其中R代表有机部分，R'代表甲基或乙基）具有不同的官能度，是镁盐的水溶液或乙醇溶液，在某些情况下是氢氧化钠的水溶液。以此方式，有机链共价键合到四面体片的硅，指向层间空间。在这种情况下，有趣的特征是，由于市场上有许多有机三烷氧基硅烷，可在层间空间中引入各种各样的有机基团，从而在各个领域中得到应用。这篇综述重点介绍了这些功能性层状化合物的最新趋势和多方面的应用。
