中文摘要： 该项目以水介质中钯纳米粒子催化的偶联反应为导向，来构筑多孔有机离子框架稳定的钯纳米催化体系。将通过离子型有机分子构筑基块的直接反应或者对中性多孔有机框架（POFs）的合成后修饰，设计合成系列含咪唑基、三氮唑基、铵基、羧基、磺酸基等离子基团的POFs。研究离子基团对POFs的亲水性能和框架结构、POFs对钯纳米粒子以及水中偶联反应的影响。通过POFs骨架、配位基团、离子基团的修饰对纳米粒子的结构和催化性能进行调控，弄清离子基团对POFs结构及其性能的影响，揭示POFs的限域、配位和静电作用对钯纳米粒子稳定性和催化活性的协同效应，阐明POFs结构与催化性能之间的内在联系，发展出水介质中反应条件温和、易于分离回收、可重复使用的高效异相催化体系，拓宽POFs在催化反应中的应用范围。预期发表论文12-15篇，申请专利2-4项，培养研究生5-8人。

英文摘要： The project will focus on the design and synthesis of ionic porous organic frameworks (POFs) as well as the exploration of the coupling reactions catalyzed by POFs-stabilized palladium nanoparticles in water. A series of ionic POFs containing imidazolium, triazolium, ammonium, carboxylate and sulfonate groups will be constructed through direct reaction of ionic organic building units or synthetic post-modification of neutral POFs. The effects of ionic groups on hydrophilicity and framework structure of POFs, as well as the effects of POFs on palladium nanoparticles and catalytic performances in water will be investigated. Meanwhile, their role in catalysis will be explored. The catalytic performances will be adjusted through variation of POFs backbone, coordination groups and ionic groups. The synergetic effects of framework confine, coordination and electrostatic interactions on stability and catalytic activity of palladium nanoparticles will be clarified. The relationship between POFs structures and catalytic performances in water will be disclosed. The highly active, easily separable and resuable catalytic system in water under mild conditions will be developed, the application scope of POFs in catalysis will be widen. This project will publish 12-15 articles, apply for 2-4 patents and train 5-8 graduates.
