Controllable Encapsulation of Fullerene-C60 into the small-aperture pore of ZIF-8 by Ball Milling

Metal-organic frameworks (MOFs) are an important class of porous materials for many application areas. Merging the unique structural properties of MOFs with intrinsic properties of fullerenes, such as electron-accepting properties and fast electron transfer, gives the opportunity to investigate new class fulleretic materials for their potential application areas such as the development of molecular electronics, photosensitizer, catalysis, etc. However, the majority of the encapsulation processes are based on post-synthetic methods, such as soaking, which results in an uncontrollable and low amount of loading due to the size of the apertures and solubility. Here we present a rapid, green, efficient, and controllable solvent-free ball-milling method to encapsulate and immobilize fullerene C60 guests into the sodalite phase of zeolitic imidazole framework-8 (ZIF-8) MOF to obtain fulleretic materials with a controllable amount of guests in the pores. [1] Computational and spectroscopic studies clarify that the movement of fullerene between the pores is energetically unfavoured.
