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其结构相关功能的基本了解，合理开发用于选择性吸附和选择性催化应用的 MOF 材料。三个研究小组结合了他们在合成/结构分析、吸附和多相催化方面的经验，以更深入地了解具有技术应用特定功能的 MOF 材料。研究重点是具有取代苯甲酸三唑酯或间苯二甲酸酯连接体的多孔 Cu-MOF，本计划的第一期。它们将被修改以调整孔隙几何形状并产生活性位点。由于吸附剂形状和尺寸的差异，孔和孔窗的尺寸和几何形状将通过连接体设计（三唑和芳香基团的取代模式）控制，以实现吸附和催化中的形状选择性。 MOF 中的活性中心将通过在框架中引入第二种类型的金属离子来产生。这种异核MOF可以通过同晶取代来合成。将研究由此产生的吸附和氧化还原催化选择性，例如烷烃/烯烃分离和烯烃氧化反应。具有不同连接基和金属位点的 MOF 上的反应物（例如 CO、O2、碳氢化合物）的吸附行为与其催化性能的相关性将有助于更深入地了解 MOF 材料的基于骨架的功能。
