Abstract
Covalent Metal-Organic Networks (CMONs) are a lesser-explored subset of coordination polymers. The covalent nature of the connection between the metal center and ligands give rise to various structural and functional advantages. The synthesis of these materials in crystalline form is encumbered by rapid rates of formation, with most CMON syntheses reported to date generating powders or amorphous materials. Our approach involves the use of a protecting group on the organic component to restrict its reactivity with a metal center. A pH controlled deprotection of the ligand decelerates the formation of metal-ligand bonds, leading to slow growth and crystal formation. These crystalline solids, characterized by single-crystal X-ray diffraction, are novel and have chromophoric character. They possess characteristic wavelengths which can be altered through pi-interaction and could be useful in the detection of foreign molecules. In this thesis, the design and synthesis of organic ligand and the covalent metal organic networks synthesized with metal salts of Cd, Hg, Pb, Cu and Ag are reported.
