Abstract Metal–organic frameworks (MOFs or also called as Porous Coordination Polymers, PCPs) are three dimensional porous materials that are constructed from the assembly of metal ion clusters and organic ligands. MOFs are of great promise materials for a variety of applications such as gas storage, separation, catalysis, etc, because of the near infinite possibilities regarding their structure, porosity, and chemical functionality.[1]
Recently, structural defects were revealed in MOF crystal structures have many interests in coordination material research fields. Since MOFs are constructed by repeating coordination bonds between metal ions (or clusters) and organic ligands, the disappearance of metal clusters or organic linker molecules generate structural defects on the frameworks.[2] The structural defects could give physically unstable frameworks, however, at the same time, allow more accessible channel or porosity to the guest molecules. Very recently, the defect engineering in MOFs pores are receiving much attention from this point of view.
In this presentation, our recent efforts for applying defect engineering to functionalization tools of MOFs will be discussed. The existence of defect in the framework could accelerate the diffusion of functionalized molecule and produce the installation of functional molecules. The scope of functionalizations and the detail kinetics along with application will be presented.
