The mechanism for ligand exchange in the zeolitic metal organic framework ZIF-8 is discussed in the context of concepts familiar to classical coordination chemistry. Kinetic studies carried out on the ligand exchange process in ZIF-8 revealed that there is a competition between associative and dissociative mechanisms. The sensitivity of the ligand substitution process to environmental factors such as the identity of the solvent will be discussed along with insight into the role that the solvent plays in facilitating the ligand exchange process. Application of these findings for the encapsulation of large guest molecules in the MOF will be discussed along with the generality of the process to other MOFs that demonstrate similar capabilities to undergo facile ligand exchange.
