2D electrically conductive metal-organic frameworks (MOFs) have broadened the scope of their applications, ranging from electrochemical energy storage to electronic devices. To rationally design these materials, it is crucial to understand d-p hybridization in metal d orbitals and ligand p orbitals. However, limited building block motifs and lack of chemical functionality in most reported 2D conductive MOFs have hindered a deeper understanding of this exciting class of MOFs. In this talk, I will discuss our recent efforts to diversify the structures and properties of conductive MOFs via manipulating d-p conjugation. First, I will present a post-synthetic methodology in which we transformed a 2D conductive MOF into a 3D framework by pillar-ligand insertion. This dimensional augmentation increased ion accessibility to the internal pores, improving gravimetric capacitance up to double. Next, I will show a strategy where we utilize the weak binding ligands at the metal node for functionalizing the MOF to transport both protons and electrons in a single platform. Lastly, a new conducting MOF employing a macrocyclic linker with an intrinsic pocket will be discussed. The resulting MOF exploits the alkyne functionality in the macrocyclic linker to host guest metal species. The strategies herein showcase our methodologies for tuning the structure and properties of 2D conjugated MOFs for tailored functions.
