项目摘要

Soft chemical reactions involving ion exchange, intercalation and deintercalation make it possible to produce compounds with homogeneous dispersion of entirely different components in a nanoscale by a recombination of pre-existing blocks. Therefore soft chemical reactions would be a most useful procedure for synthesis of new functional inorganic-organic complexes with sophisticated structures. In this study several soft chemical reactions were applied to various compounds including mainly layred structure.Almost all of layred molybdenum bronzes have been inactive to soft chemical reactions. Blue potassium molybdenum bronze was found for the first time to undergo intercalation of n-alkylamines after hydrogenation and subsequent hydration. On the other hand, copper molybdenum bronze took up n-alkylamines and pyridine without any pretreatment. The former reaction is thought to be an acid-base reaction, while the latter is not an acid-base reaction nor an ion exchange. The electric conduct … More ivity of the bronzes was increased by the order of 10^4 on the intercalation. Although aniline molecules were polymerized in the interlayr spaces of VOPO_4・2H_2O,the electric resistance of the product was very high because of low degree of polymerization of aniline.Cointercalation of organic bases involving aniline as one of base to layred aluminum dihydrogentriphosphate-I and zirconium phosphonate phosphates were carried out in order to prepare nanoporous inorganic-organic complexes. During pyrolysis of the cointercalation compounds aniline was found to be removed in the lower temperature range than other organic moiety, leaving effectively voids behind. This fact may suggest the possibility of a new synthetic route for inorganic-organic nanoporous materials.A new strategy to control the negative charge density on a layr of oxide was proposed by preparation of H_<1-y>TaWO_<6-y/2>・nH_2O.The amount of oxygen vacancies were varied in the wide range and a clear dependence of arrangement of n-alkyldiamines in the interlayr spaces on the charge density was shown.

软化学反应涉及离子交换，插入和去解剖学使得通过预先存在的块的重组重组在纳米级中与完全不同成分的均质分散体产生化合物。因此，软化学反应将是与复杂结构合成新功能无机有机配合物的最有用的程序。在这项研究中，将几种软化学反应应用于包括主要铺设结构在内的各种化合物。几乎所有铺设的钼古铜色都对软化学反应无效。在氢化和随后的水合后，首次发现了蓝钾钼青铜。另一方面，铜钼青铜占据了N-烷基胺和吡啶，没有任何预处理。前反应被认为是一种酸碱反应，而后者不是酸碱反应，也不是离子交换。电动行为…在插入上增加了10^4的铜管授权。尽管在VOPO_4 ・2H_2O的层间空间中聚合了苯胺分子，但由于苯胺的聚合程度低，产物的电阻非常高。有机基础的聚合度较低。涉及苯胺的有机基础化，该基础是硫酸二氢二氢磷酸二氢含量磷酸二氢含量磷酸含量的基础之一。纳米多孔无机有机络合物。在重合化合物的热解中发现，苯胺在温度范围较低的情况下被去除，而不是其他有机部分，从而有效地排出了空隙。这一事实可能表明，通过制备H_ <1-y> tawo_ <6-Y/2> tawo_ <6-Y/2> ・NH_2O，提出了一种新的合成途径，以控制氧化物上的负电荷密度的新策略。显示了电荷密度。较少的
