Abstract
Structural analysis of a solid-state material is vital because the structure often determines the physical (or chemical) properties of the material. An understanding of the relationship between structural components and bulk properties can be used to design materials with specific properties. To achieve such understanding, two things are required: a rigorous structural analysis method and a study of the properties of materials with noteworthy structural features. In this thesis, the author reviews 44 pyridyl porphyrin frameworks in an effort to determine how these framework structures are formed, and if any overreaching trends can be observed. The observed trends are used to develop a method to analyze pyridyl porphyrin frameworks based on the types of porphyrins used, the metal node used, and the metal-to-porphyrin ratio. The structures of two new frameworks (MPF-3 and E-MOF-1) are also analyzed and tested for their structural flexibility. The structural features of each framework are correlated to the property being examined (flexibility). The type of flexibility demonstrated is strongly related to the structure of the individual framework. The structural analysis of the frameworks presented here is a small but significant step towards the rational design of flexible metal-organic frameworks. Advisor: Wonyoung Choe
