项目摘要

In order to establish the synthetic ways of intercalation compounds having possible application as functional materials, various intercalation compounds were prepared by using appropriate guests and hosts. The following results were obtained.1. A viologen was intercalated into the interlayer space of vanadium pentoxide hydrate chemically (by ionーexchange) and electrochemically.2. When tris (2,2'-bipyridine) metal complexes were allowed to react with K_4Nb_6O_<17>, potassium ions were replaced with the complexes ; however, the tris-form complexes transformed into bisーform ones during the reaction. On the contrary, when potassium ions were exchanged for alkylammonium ions in advance, the complexes were incorporated in the interlayer space as trisーform ones. K_4Nb_6O_<17> has two kinds of interlayers, so that the intercalation compound containing the complexes in one kind of interlayers and that containing in both kinds of interlayes can be prepared.3. When sodium ions in synthetic sodium polysilicate of kanemite were exchanged for trimethylalkylammonium ions, the layers deformed to form three dimensional network. Further heat treatment resulted in the formation of microporous materials having narrow pore size distribution.4. Anionic porphyrin and dyes were successfully intercalated into the interlayer space of hydrotalcite, which has anionーexchange property.5. Some kinds of guests (acrylamide, alkylammonium salts, and alkylamines) were intercalated into montmorillonite by solidーsolid reactions easily. Similarly, 2,2'-bipyridine was intercalated into transition metalーform montmorillonites to form tris (2,2'-bipyridine) metal complexes in the interlayer space.

为了探索具有功能材料应用前景的插层化合物的合成方法，采用合适的客体和主体制备了多种插层化合物。得到以下结果.通过化学（离子交换）和电化学方法将紫精插层到五氧化二钒水合物的层间.当三（2，2 ′-联吡啶）金属配合物与K_4Nb_6O_反应时，K_4Nb_6O_取代了K_4Nb_6O_，<17>但在反应过程中，K_4Nb_6O_与三（2，2 ′-联吡啶）金属配合物转变为二（2，2 ′-联吡啶）金属配合物。相反，当钾离子预先交换烷基铵离子时，配合物以三聚体形式进入层间空间。K_4Nb_6O_2<17>具有两种夹层，因此，在一种夹层中含有复合物的插层化合物和在两种夹层中含有复合物的插层化合物都可以被取代.用三甲基烷基铵离子交换合成的钾镁石聚硅酸钠中的钠离子，使层间发生形变，形成三维网络结构。进一步热处理导致形成具有窄孔径分布的微孔材料。阴离子卟啉和染料成功地插层到水滑石层间，水滑石具有阴离子交换性能.几种客体（丙烯酰胺、烷基铵盐和烷基胺）可以通过固-固反应插层到蒙脱土中。同样地，2，2 '-联吡啶插入过渡金属阴离子型蒙脱石中，在层间空间中形成三（2，2'-联吡啶）金属配合物。
