Application

Isophthalic acid can be used as a reactant to prepare:
  • Poly(m-phenyleneisophthalamide) by polycondensation with m-phenylenediamine via thermal solid-phase polymerization reaction.

It can also be used as a ligand to synthesize:
  • Metal coordination polymers by hydrothermal and sonochemical process.
  • Isophthalic acid-zirconium(IV) nanocomposite, which is used as a precursor to prepare crystalline tetragonal ZrO2 via thermal decomposition method.

Metal organic frameworks (MOFs) are among the most exciting materials discovered recently, attracting particular attention for their gas-adsorption and -storage properties. Certain MOFs show considerable structural flexibility in response to various stimuli. Although there are several examples of 'breathing' MOFs
