During the synthesis of the described MOFs, the Zr(IV) and ellagate ligands likely organize around the OSDA, directing the MOF structure based on its size, shape and host-guest interactions. As such, hydrogen bonding and π-π stacking likely play significant roles in the assembly of specific structures in addition to electrostatic and van der Waals interactions. Considering this diversity of interactions, the role of OSDAs in this Zr-elllagate system is rather different than that observed in templated inorganic porous materials, owing to the presence of both inorganic and organic species in the MOF materials.
