Spectroscopic Behavior

The crystal lattice of the title compound, C34H22O2·2C3H7NO, at 173 K has monoclinic (P21/n) symmetry. Molecules are located on crystallographic centers of symmetry and have approximate non-crystallographicmmmsymmetry, indicating that in solution the chemical and spectroscopic behavior would be that of aD2hmolecule. The compound has applications in gas-separation membranes fabricated from polymers of intrinsic microporosity (PIM). The compound is the product of reduction of the corresponding quinone by Na2S2O4in DMF/NaHCO3.

Potential Use

A series of nine polymers of intrinsic microporosity (PIMs) derived from different bis-catechol monomers and 2,3,7,8-tetrafluoro-5,5’,10,10’-tetraoxidethianthrene (TOT) were synthesised and tested for their potential use as gas separation membranes. As...
