Aim of this joint project is the rational development of MOF materials for applications in selective adsorption and selective catalysis based on a fundamental understanding of their structure-related functions. Three research groups combine their experience in synthesis/structural analysis, sorption and heterogeneous catalysis to achieve a deeper knowledge on MOF materials with specific functions for technical applications.The investigations focus on porous Cu-MOFs with substituted triazolyl benzoate or isophthalate linkers, developed in the first period of this program. They will be modified in order to adjust the pore geometry and to generate active sites. Size and geometry of the pores and the pore windows will be controlled by linker design (substitution pattern of the triazole and aromatic groups) in order to achieve shape selectivity in adsorption and catalysis, due to differences in shape and size of the adsorptives. Active centres in the MOFs will be generated by introducing a second type of metal ions into the framework. Such heteronuclear MOFs can be synthesized by isomorphous substitution. The resulting selectivity in adsorption and redox catalysis will be studied, e.g., for alkane/alkene separation and alkene oxidation reactions. The correlation of the sorption behavior of the reactants (e.g. CO, O2, hydrocarbons) on MOFs with different linkers and metal sites to their catalytic properties will provide a deeper understanding of the framework-based functions of MOF materials.

该联合项目的目的是基于对结构相关功能的基本了解，将MOF材料的合理开发用于选择性吸附和选择性催化。三个研究小组结合了他们在合成/结构分析，吸附和异质催化中的经验，以实现具有技术应用的特定功能的更深入了解MOF材料。该研究的重点是用取代的三唑酯苯甲酸酯或同磷酸酯链接的多孔CU-MOF，在该计划的第一阶段中开发。它们将进行修改，以调整孔的几何形状并生成活动位点。由于吸附剂的形状和大小差异，孔和孔窗的大小和几何形状将通过接头设计（三唑和芳族组的替换模式）来控制形状的选择性。通过将第二种类型的金属离子引入框架中，将生成MOF中的活动中心。这种异核MOF可以通过异态取代合成。将研究产生的吸附和氧化还原催化的选择性，例如，用于烷烃/烷烃分离和烯烃氧化反应。具有不同接头和金属位点与其催化特性的MOF上反应物（例如CO，O2，碳氢化合物）的吸附行为的相关性将为MOF材料的基于框架的功能提供更深入的了解。
