Electrically conductive metal-organic frameworks (EC-MOFs) are among the most promising materials due to their tunable structures, properties, and diverse functions. However, the lack of comprehensive understanding of their structure-property relationship hinders the development of EC-MOFs. My dissertation focuses on the design, construction, and structure-property relationship studies of EC-MOFs.

Chapter 1 describes how MOFs' structural features and compositions affect the electronic properties and demonstrates conductive mechanisms and the corresponding design strategies to develop EC-MOFs.

Chapter 2 describes the synthesis, characterization, electronic and optical properties of four novel alkali-metal-based (Na, K, Rb, and Cs) 3D-MOFs with continuous tetrathiafulvalene tetracarboxylate (TTFTC) π-stacks, systematicly demonstrating how the structures of MOFs, TTFTC•+ population and intervalence charge transfer (IVCT) interaction affected their band gaps and electrical conductivity.

Chapter 3 depicts a novel design strategy to enhance the bulk electrical conductivity of 2D graphitic MOFs by simultaneously remaining in-plane and enhancing out-of-plane charge transport through built-in alternating π-donor/acceptor stacks of electron-rich hexaaminotriphenylene (HATP) ligands and non-coordinatively intercalated π-acceptors hexacyano-triphenylene (HCTP) molecules.

Chapter 4 describes design, synthesis, and structure-property relationship studies of a novel 2D Cu3(HOTP)(HHTQ) MOF based on a π-donor 2,3,6,7,10,11-hexahydrotriphenylene (HOTP) ligand and a π-acceptor 2,3,7,8,12,13-Hexahydroxytricycloquinazoline (HHTQ) ligand. The resulting framework featured continuous out-of-plane π-D/A stacks and in-plane hexagonal π-D-A sheets, promoting through-space and through-bond charge transport, respectively, which gave rise to a bulk electrical conductivity than pristine Cu3(HOTP)2 and Cu3(HHTQ)2.

Finally, Chapter 5 describes the transformation of a collapse-prone, electrically insulating MOF-74 analog into structurally more stable, porous, and electrically conductive MOF/PEDOT composites.
