Abstract

Electrically conductive metal-organic frameworks (EC-MOFs) have become an important research topic in recent years in large part due to their charge transport properties in combination with high crystallinity and permanent porosity. This thesis focuses primarily on the post-synthetic modification of an EC-MOF, namely Cu-THQ (THQ = tetrahydroxy-1,4-benzoquinone), to gain mechanistic understanding of the structure-property relationship in regard to electrical conductivity. The main project used dimensional augmentation of 2D Cu-THQ to 3D via pillar- ligand insertion in order to disrupt one of the two primary charge transport pathways. Analysis of the new materials’ structure and electrical conductivity measurements gave insight into the dependence of bulk electrical conductivity on the minor charge transport pathway. The results also open doors to introduce functionalities within EC-MOFs, more so than just structural pillaring, which may create huge potential in the use of chemical sensing or electrochemical catalysis.
