In the present work, three “ship in a bottle” Porph@MOMs are reported as biomimetic oxidation catalysts for different reactions. These frameworks are constructed from trimesic acid and metal ions (M = Fe, Co and Mn) in which tetra(N-methyl-4-pyridyl)porphyrin (MTMPyP) is encapsulated within the cavities. Additionally, the catalytic activities of the corresponding homogeneous compounds, FeTMPyP, CoTMPyP and MnTMPyP, and the frameworks without porphyrins within the cavities were investigated in the foregoing oxidation reactions. The prepared 3D porous structures have the ability to control selectivity toward the desired product. Furthermore, they are capable of acting as effective peroxidase mimics, which successfully catalyze the oxidation of diverse olefins as well as hydrocarbons using TBHP as an oxidant. The heterogeneous catalysts significantly enhance conversion in contrast to their corresponding homogeneous systems. Remarkably, an insight into the catalyst behavior was gained from the proposed mechanism based on the reversal of selectivity. Investigation of the stability and reusability of the catalysts revealed the heterogeneity character of the catalyst with no desorption during the course of oxidation reactions. The high yields, clean reactions, high thermal stability and reusability of the catalysts make them good candidates for heterogeneous catalysts in various oxidation reactions.

“瓶装船运” Porph @ MOMs是高效的催化剂，可选择性地控制氧化并深入了解异质和均质环境中的不同机制†

在目前的工作中，据报导三种“瓶装” Morph @ MOM作为仿生氧化催化剂，可用于不同的反应。这些骨架由偏苯三酸和金属离子（M = Fe，Co和Mn）构成，其中四（N-甲基-4-吡啶基）卟啉（MTMPyP）封装在腔体内。另外，在上述氧化反应中研究了相应的均相化合物FeTMPyP，CoTMPyP和MnTMPyP的催化活性，以及​​在腔内没有卟啉的骨架。制备的3D多孔结构具有控制对所需产品的选择性的能力。此外，它们能够充当有效的过氧化物酶模拟物，使用TBHP作为氧化剂可成功催化各种烯烃以及烃类的氧化。与它们相应的均相系统相比，非均相催化剂显着提高了转化率。值得注意的是，基于选择性的逆转，从提出的机理中获得了对催化剂行为的深入了解。对催化剂的稳定性和可重复使用性的研究揭示了催化剂的异质性，在氧化反应过程中没有解吸。催化剂的高产率，清洁反应，高热稳定性和可重复使用性使其成为各种氧化反应中非均相催化剂的良好候选者。
