The influence of composition and textural characteristics of a family of ultra-small isoreticular UiO-type metal-organic frameworks (MOFs) with different functionalized and extended linkers on their catalytic performance is evaluated. Two direct amide bond formations across four different substrates (benzylamine + phenylacetic acid and aniline + formic acid) are employed as proof-of-concept reactions to test the activity of the Zr-MOF nanoparticles. The reaction rates of amide bond formation are evaluated against physico-chemical properties such as crystallinity, porosity, particle size or linker functionality, alongside the Lewis acid and hydrophobic properties of the MOFs, in order to gain insights into the catalytic mechanism and optimal properties for its enhancement.
评估了一系列具有不同功能化和延长连接体的超小等规UiO型金属有机框架(MOF)的组成和结构特征对其催化性能的影响。通过在四种不同底物(苄胺+苯乙酸和苯胺+甲酸)上进行两种直接酰胺键形成反应,作为概念验证反应来测试Zr-MOF纳米颗粒的活性。针对MOF的物理化学性质(如结晶度、孔隙率、粒径或连接体官能团)以及路易斯酸性和疏水性,评估酰胺键形成的反应速率,以便深入了解催化机制及其增强的最佳性能。
