项目摘要

Although numerous porous coordination networks have been synthesized to date, the functionalization of the pores at will without changing the network frameworks is still a difficult task in spite of the high designability of organic ligand components. This is because the porous network formation is very sensitive to the ligand structure. Namely, the introduction of even a small functional group to the ligand often brings about the formation of completely different, unpredictable network structures. We have previously synthesized a unique porous coordination network in which the pores are surrounded by aromatic bricks. 3 The bricks consist of alternatively layered 2, 4, 6-tris(4-pyridyl)-1, 3, 5-triazine (1) and triphenylene (2a); the former, 1, forms infinite 3D network via coordination to ZnI_2, whereas the latter, 2a, is involved in the 3D framework without forming any covalent or coordination bonds with other components. Here, we report that the non-covalently intercalated 2a in thi … More s porous complex can be replaced with several functionalized triphenylenes without causing any change in the porous network structure. In these porous complexes, intercalated triphenylenes are regarded as the cartridges of functional groups. We emphasize that the facile control of the pore nature by simply replacing the cartridge is a new approach to the library synthesis of a family of porous networks, which we would like to term "cartridge synthesis". For the first time, this study demonstrates at atomic level that slight pore modification makes remarkable differences in alcohol recognition capability. Selective molecular separation is one of important issues for porous coordination networks. Especially alcohol molecules are urgent subjects related with bio-fuel production. At this moment zeolite-type materials have been used as a separator. One of intriguing questions is that alcohol separation is not always related with the pore size of the separator. In order to design efficient materials for alcohol separation, it is essential to know how alcohol molecules can be recognized and interact inside of pores. Less

尽管迄今为止已经合成了许多多孔协调网络，但尽管有机配体组件的高可设计性，但随意不改变网络框架的孔的功能仍然是一项艰巨的任务。这是因为多孔网络形成对配体结构非常敏感。也就是说，即使引入一个小型功能组，配体通常会带来完全不同的，不可预测的网络结构的形成。我们以前已经合成了一个独特的多孔协调网络，其中孔被芳香砖包围。 3砖由替代层的2、4、6-三（4-吡啶基）-1、3、5-三嗪（1）和triphenylene（2a）组成；前者1通过与Zni_2的协调形成无限的3D网络，而后者2a则参与了3D框架，而无需与其他组件形成任何共价或协调键。在这里，我们报告说，在Thi中非共价插入的2a……可以用几个功能化的三苯基代替更多的多孔复合物，而不会导致多孔网络结构发生任何变化。在这些多孔复合物中，插入的三苯基被认为是官能团的墨盒。我们强调，通过简单地替换墨盒是库合成多孔网络家族的一种新方法，我们想将其称为“墨盒合成”，从而使孔本质的轻松控制是一种新的方法。这项研究首次在原子水平上表明，稍微修饰孔隙孔的差异显着差异。选择性分子分离是多孔协调网络的重要问题之一。尤其是酒精分子是与生物燃料生产有关的紧急受试者。目前，沸石型材料已被用作分离器。有趣的问题之一是，酒精分离并不总是与分离器的孔径有关。为了设计有效的酒精分离材料，必须知道如何在毛孔内识别酒精分子并相互作用。较少的
