SPP 1362: Porous Metal-Organic Frameworks

点击翻译按钮获取中文摘要

The Priority Programme concentrates on the synthesis, the physical properties and the specific integration of functionality into Metal-Organic Frameworks (MOFs), a new class of porous materials surpassing significantly the adsorption capacity of established materials such as activated carbons and zeolites. They are characterised by a modular construction principle allowing for a rational design of custom made pore systems. Using suitable building blocks, the integration of specific interactions for molecules inside the framework shall be realised for the storage, sensing, transformation or separation of molecular species inside MOFs. In this way, new materials for energy storage (for example hydrogen or methane) will be constructed. For sensor materials, a change of physical properties should be used for the detection of molecules. For the chemical transformation, materials are important, having specific active catalytic sites in the framework or the pores. In all cases, the focus is to achieve a basic understanding of the interactions of the framework and the adsorbed or reacting molecules. In this context, the experimental determination of the preferred adsorption sites and the dynamics of molecules inside the pore system are crucial. For this purpose, also modelling using modern theoretic methods is needed. In order to enhance the interdisciplinary exchange between chemists, materials scientists, physicists and engineers, generally only such projects will be funded, providing a synergistic cooperation of two or three Principal Investigators with different expertise in the following areas of competence:
