Figure 1. A: The self-assembly of modifiable organic linkers with zinc cations to generate a bifunctionalizable metal-organic framework (MOF) material, KSU-1. B: Schematic representation of the sequential, independent functionalization of KSU-1 to yield a uniformly multifunctional MOF material.
In our NSF-funded research we have developed a strategy to uniformly multifunctionalize MOFs post-synthesis (Figure 1, Link). We have recently extended this work with the use of orthogonal functionalization chemistry which allows us to generate uniformly multifunctional MOFs simultaneously in one pot (Link). Our uniform multifunctionalization strategy depends on our ability to construct mixed-linker frameworks that have large enough channels to accommodate additional functionality. We have recently provided evidence to support the theory that the use of organic linkers that have H-bonding substituents can prevent interpenetration of frameworks. We synthesized a non-catenated, mixed-ligand MOF that, to our knowledge, has the largest pore volume and lowest density of its topology (Scheme 1, Link).
