This study explores the synthesis and characterization of novel organometallic ligands, focussing on 2,3,8,9,14,15-hexahydroxy-5,6,11,12,17,18-hexaazatrinaphthylene (HATNA-[OH]6) and its precursors. This is due to their utility as electrodes which enable high performance of next-generation sodium-ion batteries via redox mechanisms, and potassium-ion batteries in the form of 2D metal-organic frameworks (MOFs). MOFs are a class of porous polymers which exhibit superior separation and adsorption properties. Thus, HATNA-[OH]6 could bring about potential uses in high-performance solar cells, batteries, permeable membrane filters and catalysis. Two synthesis routes were attempted to create the HATNA-[OH]6 product, but neither pathway was able to obtain the final product by the end of the project due to unexpected experimental difficulties. During the process, H-NMR and IR analysis of the products were done throughout to verify the composition of the products. Possible solutions to these experimental issues are thus proposed. Developing the synthesis of HATNA-[OH]6 will facilitate the design and development of next-generation batteries and MOFs with customized properties that can be used in solar cells, batteries, and membrane filters by tweaking different parameters within HATNA-[OH]6-based MOFs.
