Application

5-Aminoisophthalic acid (AIPA) can be used as a starting material to prepare:
  • Poly(5-aminoisophthalic acid) by oxidative polymerization reaction.
  • Poly(benzimidazole-co-aniline) (PBIANI) by condensation polymerization with 3,3′-diaminobenzidine via poly(5-aminoisophthalic acid) as a key intermediate.

It can also be used as a blended material with polyvinylalcohol to prepare silica-functionalized composite membranes for diffusion dialysis applications. AIPA based metal-organic framework (MOF) can be modified with various functional groups for different applications.

Two stable supramolecular microporous cobalt(II) polymers, namely [Co(HAIP)2]n.3nH2O (1) and [Co(AIP)(H2O)]n (2), AIP = 5-aminoisophthalate, were hydrothermally synthesized and characterized by single-crystal X-ray diffraction, IR spectra, thermogravimetric analyses, and variable-temperature magnetic susceptibility measurements. The two complexes are constructed from the
