The activity of two bifunctional metal–organic frameworks (MOFs) with IRMOF‐9 topology that contain amino, phosphine oxide and methyl groups is described. The amino group acts as an active site for the Knoevenagel condensation of ortho, meta or para nitrobenzaldehyde and malononitrile, while the non‐active site diphenylphosphoryl or methyl group moderate the spatial characteristics inside the MOF pores
描述了具有IRMOF-9拓扑结构的两个双功能金属有机框架(MOF)的活性,这些框架包含氨基,氧化膦和甲基。氨基充当邻位,间位或对位硝基苯甲醛和丙二腈的Knoevenagel缩合的活性位点,而非活性位点二苯基磷酰基或甲基则可调节MOF孔内部的空间特征。官能团诱导独特的催化反应。与苯胺相比,当由MOF催化时,反应活性得到增强,而氧化膦则阻碍了邻位异构体产物的形成。
