Construction reaction of bowl-type vanadium oxide molecule by template reaction

金属氧化物是现代社会高科技领域的热门材料之一，具有超导性、磁性或半导体性、催化剂等特性。当我们寻找所有这些材料中最好的特性时，许多这些材料都变成了金属氧化物，我们需要从分子水平上理解这些特性。金属氧化物分子的合成看似简单，但长期以来对化学家来说是一个挑战，未开发的世界是哀号的。本研究发现了氧化阴离子与金属原子配位的无机配合物化学，证明了配位化学可以扩展到纯无机氧化物化学的领域。无机配合物是由多钒氧酸盐和金属阳离子作为路易斯酸结合而成的。金属源的路易斯酸促使偏钒酸盐三聚体或四聚体在乙腈溶液中缩合反应。在非水溶液中合成了an、Ni（II）、Cu（II）和Zn（II）的纯有机配合物，并合成了具有冠型氧化阴离子配体的各种氧化物分子。本研究中最有趣的发现是手性无机分子的发现。当我们在硝酸模板存在下缩合钒酸盐时，我们发现通过硝酸模板在链的两端被V05锥体单元覆盖，形成了两条十八氰酸盐链。另一种观点认为，第一个双螺旋无机分子已经出现。钒基氧化物的新化学研究具有战略意义，可以从分子化学的角度来理解氧化物的各种性质。本研究探索了氧化分子的化学性质，并实现了许多有趣的盘状、笼状、手性氧化分子的形成，进一步的研究将为功能材料的研究提供延伸。

Metal oxide is one of a popular material in high-tech world in modern society such as superconductivities, magnetic or semiconductor properties, and catalysts. When we look for the best properties of all, many of these materials are turning up to be metal oxides, and need to understand those properties from the molecular level. The synthesis of metal oxide as a molecule is seemingly easy, but is a challenge for a chemist for a long time, and unexplored world is wailing. In this study, we discover the chemistry of inorganic complex in which the oxide anion is coordinated to the metal atoms, and we proved the coordination chemistry can be expanded to the world of pure inorganic oxide chemistry. The inorganic complex was achieved by the combination of polyoxovanadates and the metal cations as Lewis acid The Lewis acidity of the metal sources prompt the condensation reaction of the metavanadate species, which is tri or tetramer in acetonitrile solution. The resulting pureinorganic complex of an, Ni(II), Cu(II), and Zn(II) have been synthesized in non-aqueous solution and various oxide molecule with crown-type oxide anion ligands were synthesized. Most of the interesting finding in this study is a discovery of the chiral inorganic molecule. When we condense the vanadate under the presence of nitrate template, we found the formation of two octadecavanadate chains through the nitrate template capped the both ends of the chain by V05 pyramidal units. In other view, the first double helical inorganic molecule had been emerged.The new chemistry of fundamental oxide of vanadium is strategic importance, and the understanding of the variety of properties in oxide can be tackled from the point of molecular chemistry. This study explorer the chemistry of oxide molecule and many interesting formation of disk, cage, chiral oxide molecule have been realized, and further studies will provide the extention toward the functional materials.
