  摘要：

  二烷氧基二氯硅烷（（RO）2SiCl2，R = 烷基）与层状硅酸盐辛硅酸盐中的层间硅烷醇基团几乎完全反应，以产生新的结晶硅酸盐结构，该结构由在硅酸盐层两侧规则排列的新五元环组成。将二烷氧基甲硅烷基引入具有规则反应位点的层状硅酸盐的层间区域，为通过软化学途径设计和构建新型结晶硅酸盐骨架提供了一种新方法。

• Molecular Manipulation of Two- and Three-Dimensional Silica Nanostructures by Alkoxysilylation of a Layered Silicate Octosilicate and Subsequent Hydrolysis of Alkoxy Groups

  A novel methodology for constructing molecularly ordered silica nanostructures with twodimensional (2-D) and three-dimensional (3-D) networks has been developed by using a stepwise process involving silylation of a layered silicate octosilicate with alkoxytrichlorosilanes [ROSiCl3, R = alkyl] and subsequent reaction within the interlayer spaces. Alkoxytrichlorosilanes react almost completely with octosilicate, bridging two closest Si-OH (or -O-) sites on the silicate layers, to form new five-membered rings. The unreacted functional groups, Si-Cl and Si-OR, are readily hydrolyzed by the posttreatment with a water/dimethyl sulfoxide (DMSO) or water/acetone mixture, leading to the formation of two types of silicate structures. The treatment with a water/DMSO mixture produced a unique crystalline 2-D silicate framework with geminal silanol groups, whereas a water/acetone mixture induced hydrolysis and subsequent condensation between adjacent layers to form a new 3-D silicate framework. The 2-D structure is retained by the presence of DMSO molecules within the swelled interlayer spaces and is transformed to a 3-D silicate upon desorption of DMSO. The structural modeling suggests that both of the 3-D silicates contain new cagelike frameworks where solvent molecules are trapped even at high temperature (up to 380 degrees C, in the case of acetone). Both 2-D and 3-D silica structures are quite different from known layered silicates and zeolite-like materials, indicating the potential of the present approach for precise design of various silicate structures at the molecular level.
