Abstract

Metal-Organic Nanotubes (MONTs) are a crystalline one-dimensional porous material that can be formed from the interaction between an organic ligand and a metal. The synthesis of this class of material is similar to its three-dimensional counterpart (MOFs) where in both cases precise choice of ligand and metal can result in the altering of material dimensions. When highlighting the differences between these two classes of coordination polymers, the exploration of MONTs has shown that they are formed anisotropically in which their one-dimensional growth causes them to be a functionally successful choice for the adjustment of organic linker synthesis and size.

Within our group, there have been many different avenues in which MONTs as a material have been investigated. MONTs have been prepared utilizing a 2, 3, and 4 column pillared approach where herein the Jenkins group the 2-column pillared approach is utilized. With the work done by the Jenkins group in the both the past and in the present, there have been a series of organic linkers specifically designed to investigate the relationship between a semi-ridgid di- triazole organic linker and an associated metal of which has generally been copper or silver. Expanding on the research of previous group members and herein this thesis, a review of particle size, composition, and more importantly, pore size is discussed.

In the past, the goal of this research group has been to identify and rationalize the ideal way to synthesize these discrete nanotubes on the bulk scale. Although this goal is still present to this day, a goal that is more pressing is highlighted within this thesis. To highlight specifically, the goal of the research herein this thesis is to accomplish the synthesis of MONTs utilizing expanded organic linkers of which could form a novel crystalline material with an expanded pore. Through the utilization of collaborations in the field, different techniques using crystallography as the basis were employed in order to fully characterize the synthesized expanded MONTs as a material.
