dc.description.abstractCovalent Organic Frameworks (COFs) are a class of 2D and 3D crystalline polymeric materials that possess high surface areas, permanent porosity, and chemical/thermal stability. These properties make COFs a promising candidate for various applications such as separations, water treatment, catalysis, and energy storage. In the last 2 decades, significant work has been done on expanding the library of available linkage chemistries that can be used to synthesize COFs. Of these, hydrazone linkages show great promise due to their high degree of crystallinity, high stability, and a large library of tunable pore substituents. However, many of the synthetic routes to produce these COFs lead to powder products that are incompatible with common solution processing techniques. This thesis focuses on processing of hydrazone linked frameworks through three methods: gelation of hierarchical aerogels of COF material is explored; a reactive additive manufacturing technique is introduced; and chemical vapor deposition (CVD) is investigated. By using this combination of techniques, I am able to create COFs in various form factors such as monoliths, grids, films, and coatings. These techniques enable the quantification of structure-property relationships of monolithic COF materials, as well as applications such as size-based separations and photocatalysis.en_US
