The design, synthesis, characterization, and evaluation of new metal-organic frameworks (MOFs) is the goal of this project. MOFs are a class of materials that combine organic ligands and metal ions to generate porous materials with defined topologies. Our focus for several years has been on the development of postsynthetic methods for the functionalization of MOFs. Postsynthetic methods, such as postsynthetic modification (PSM), postsynthetic deprotection (PSD), and postsynthetic exchange (PSE) are useful approaches to altering the physical properties of MOFs and generate MOF materials with new properties, including catalytic function. Prior work from our lab has focused on replacing the organic ligand component with a 'metalloligand' (e.g. coordination complex) that can impart new spectroscopic properties to the MOF. These studies largely focused on dipyrromethene (dipyrrin) complexes as building blocks, and as such we have a general interest in developing the coordination chemistry of these interesting pyrrolic ligands. Most recently, we have developed an interest in the interface between MOF and polymer materials, including a new hybrid we describe as polyMOFs (see figure below) and mixed-matrix membranes (MMMs) derived from MOFs.
