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.

The liquid/solid interface provides an interesting medium for molecular self-assembly and scanning tunneling microscopy is the preferred technique to analyse the structural features of the surface-supported self-assembled monolayers in this medium. An interesting aspect is the phenomenon of molecular dynamics
