Pillar[5]quinone Derived Multi-Microporous Organic Polymers for Radioactive Organic Iodide Capture and Storage

Topic:

Scientific Achievement 

Pillar[5]quinone derived multi-microporous organic polymers with hydrophenazine linkages (MHP-P5Q) were synthesized via a solvent and catalyst-free mechanochemical method.

Significance and Impact

The multi-microporous polymers are promising candidates for radioactive organic iodide capture and storage as a result of the synergistic effect of both chemical adsorption and physical adsorption. 

Research Details

  • Mechanochemical synthesis of hydrophenazine-linked porous organic polymer using benzoquinones and diamines.
  • Pillar[5]quinone derived polymer (MHP-P5Q) displays a unique three-step N2 sorption isotherm with three distinct pore size distribution.
  • MHP-P5Q has a superior performance in the capture and storage of CH3I due to the presence of pillararene cavity as additional binding sites.
