Abstract

The unique postsynthetic functionalization characteristic of metal–organic frameworks (MOF), especially those that possess a free -NH₂ group, encourages researchers to design nanocatalysts based on MOF with crystalline architecture. The present work reports a new nanocatalyst of UiO-66-NH-Glu-Mla@Pd, focusing on its design, synthesis, functionalization, and application in the Suzuki coupling reaction. UiO-66-NH₂ MOF was successfully synthesized via a solvothermal method and then functionalized with organic reagents of glutaraldehyde (Glu) and melamine (Mla) using the cocondensation and postsynthesis grafting strategies. Finally, the UiO-66-NH-Glu-Mla was decorated by palladium nanoparticles to generate UiO-66-NH-Glu-Mla@Pd. These modifications turn a low-active MOF into an ideal nanocatalyst with high catalytic activity in the Suzuki reaction. The results showed that the efficiency and durability of structure UiO-66-NH-Glu-Mla@Pd was still high after at least six consecutive uses.

基于功能化金属-有机骨架修饰的钯纳米可再生催化剂合成联芳基衍生物

金属有机骨架（MOF）独特的合成后功能化特性，特别是那些具有游离nh2基团的金属有机骨架，鼓励研究人员基于MOF设计具有晶体结构的纳米催化剂。本文报道了一种新型纳米催化剂UiO-66-NH-Glu-Mla@Pd，重点介绍了其设计、合成、功能化及其在铃木偶联反应中的应用。采用溶剂热法成功合成了uuo -66- nh2 MOF，并用戊二醛（Glu）和三聚氰胺（Mla）有机试剂进行了缩聚和合成后接枝修饰。最后，用钯纳米粒子修饰UiO-66-NH-Glu-Mla生成UiO-66-NH-Glu-Mla@Pd。这些修饰使低活性的MOF成为铃木反应中具有高催化活性的理想纳米催化剂。结果表明，UiO-66-NH-Glu-Mla@Pd结构在至少连续使用六次后，其效率和耐久性仍然很高。

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
