In this project, we propose to develop an entirely new class of hybrid material that contain regions of both zeolite and metal-organic framework (MOF) - we call these materials ZeoMOFs. Microporous materials, including zeolites and MOFs, make up one of the most important classes of material in current research: zeolites are heavily used in industry and MOFs are some of the most exciting materials to have been prepared over the last two decades. While their structural architectures look similar (both types of material are porous) their chemistries are quite different. This means that a material that was part zeolite and part MOF would undoubtedly have some very interesting properties. However, the synthesis of such an intimate ZeoMOF hybrid is difficult, and likely impossible, using traditional approaches because of the incompatibility of their synthesis conditions. This means we have to design a new approach. In this project we will develop some of the recent synthetic work we have completed in the area of manipulation of structures using the ADOR process. In this project we will use these recent developments to first prepare zeolite layers. Then under carefully controlled conditions where the zeolite layers remain stable we use use the 'softer' conditions used in MOF synthesis to intercalate MOF species in between the zeolite layers and connect them together. The initial materials prepared are likely to be disordered but as we gain the necessary experience with the chemistry we expect to prepare more crystalline porous solids. The materials will be challenging to characterise, and we will use a combination of scattering and magnetic resonance (and other) techniques to fully understand the structure of the materials and then we will complete an activity aimed at understanding the properties of the new solids, with particuar focus on ascertaining how the porosity, catalytic and adsorption (e.g. for separation) properties are modified compared to zeolites and MOFs.

在这个项目中，我们建议开发一种全新的杂化材料，包含沸石和金属有机骨架(MOF)区域-我们将这些材料称为ZeoMOF。微孔材料，包括沸石和MOF，构成了当前研究中最重要的一类材料：沸石在工业上被广泛使用，MOF是近二十年来制备的最令人兴奋的材料之一。虽然它们的结构结构看起来很相似(两种材料都是多孔的)，但它们的化学成分却截然不同。这意味着，一部分是沸石，一部分是MOF的材料无疑会有一些非常有趣的性质。然而，由于合成条件的不相容，使用传统方法合成如此亲密的ZeoMOF杂化是困难的，甚至可能是不可能的。这意味着我们必须设计一种新的方法。在这个项目中，我们将开发一些最近完成的合成工作，这些工作是在使用ADAR过程的结构操纵领域中完成的。在这个项目中，我们将首先利用这些最新的发展来制备沸石层。然后，在沸石层保持稳定的精心控制的条件下，我们使用在MOF合成中使用的“较软”条件，在沸石层之间插入MOF物种并将它们连接在一起。最初制备的材料可能是无序的，但随着我们获得必要的化学经验，我们有望制备更多结晶的多孔性固体。材料的表征将是具有挑战性的，我们将使用散射和磁共振(及其他)技术的组合来全面了解材料的结构，然后我们将完成旨在了解新固体属性的活动，特别是重点确定与沸石和MOF相比，孔隙率、催化和吸附(例如，用于分离)属性是如何被修改的。
