Metal-organic frameworks (MOFs) are a new class of hybrid porous materials that are very attractive to design new type of catalysts. Because of their well-defined structure and site isolation, MOFs are found to be a very appropriate class of model solid catalysts. Their covalent post-synthetic modification is a powerful tool for obtaining highly sophisticated functionalized structures from amino-containing frameworks. The covalent post-synthetic modification of a variety of MOF structures, such as SIM-1, MIL-68, MIL-101 or UiO-66, is carried out in novel fashions, the structures remaining crystalline and porous after functionalization. On one hand, we are able to modify the environment of active sites present in the native MOF framework to enhance the catalytic activity. On the other hand, we graft organometallic or chiral organocatalytic species inside MOF cavities to get unprecedented catalytic activities.
