项目摘要

Most of assembled metal complexes reported hitherto are constructed with a combination of appropriate bidentate organic spacers and trigonal, tetrahedral, and octahedral metal templates, in which the metal ions are used as joining parts. However, these are disadvantage from the viewpoint that the metal ions are not available as the reactive site and the formed nano-pores cannot change according to the molecular sizes or shapes. These problems will be settled by the use of the metal complexes modified with non-covalent interaction sites such as hydrogen bonding and hydrophobic ones. Previously, we reported some dinuclear metal complexes linked with a triple hydrogen-bond between the biguanidato and biuretato complexes. The objective of this research project is to construct novel nano-porous transition metal complexes assembled with only the triple-hydrogen bonding and hydrophobic interactions and to establish a new methodology for the preparation methods. In this project, we designed and prepared one-, two-, and three-dimensional coordination frameworks, such as helical, brick wall, ladder, honeycomb, square grid, parquet, diamondoid and more complicate connective compounds. The construction of coordination polymers with nano-porous frameworks using these methodologies are of great interest due to their potential functionalities such as size-selective molecular absorption, shape-selective catalysis, and ion-exchange. Here, we succeeded in preparation of a novel nano-porous metal complex that has been constructed from the metal complexes bearing non-covalent interaction groups such as hydrogen bonding and hydrophobic ones.

迄今为止报道的大多数组装金属配合物都是由适当的二齿有机间隔基与三角形、四面体和八面体金属模板组合而成，其中金属离子作为连接部分。然而，从金属离子不能用作反应位点并且所形成的纳米孔不能根据分子尺寸或形状而改变的观点来看，这些是不利的。这些问题将通过使用非共价相互作用位点如氢键和疏水位点修饰的金属配合物来解决。在此之前，我们报道了一些双核金属配合物，它们是通过双胍基和缩二脲基配合物之间的三重氢键连接的。本研究的目的是构建仅通过三氢键和疏水相互作用组装的新型纳米多孔过渡金属配合物，并建立一种新的制备方法。在本项目中，我们设计并制备了一维、二维和三维的配位骨架，如螺旋、砖墙、梯形、蜂窝、方格、拼花、菱形以及更复杂的连接化合物。由于配位聚合物具有尺寸选择性分子吸附、形状选择性催化和离子交换等潜在功能，使用这些方法构建具有纳米多孔框架的配位聚合物引起了极大的兴趣。在这里，我们成功地制备了一种新型的纳米多孔金属配合物，该配合物由具有非共价相互作用基团如氢键和疏水基团的金属配合物构建而成。
