2,5-Dipropoxyterephthalohydrazide (CAS 2143456-42-0) is a dipropoxybenzene monomer bearing a hydrazide group at each para position. Researchers use it as a ligand for building covalent organic frameworks (COFs), especially those linked through hydrazone bonds, such as COF-42 prepared with triformylbenzene and COF-43 prepared with triformylphenylbenzene.
Combined with 2,4,6-triformylphloroglucinol, the compound gives β-keto-enamine 2D-COFs. These frameworks form when the initial enol structure undergoes an irreversible tautomerization to the keto form. Such COFs have been studied together with carbon nanotubes decorated with ruthenium (Ru) nanoparticles as a cathode for Li-CO2 batteries, reaching a capacity of 27348 mAh/g at a current density of 200 mA/g.
The hydrazide groups react readily, which makes the linker convenient for cross-linked COF and MOF networks. It is supplied at >98% purity as an off-white to pale yellow fluffy powder, with a molecular weight of 310.35 g/mol.
