A Spirobifluorene-Based Polymer of Intrinsic Microporosity with Improved Performance for Gas Separation

A highly gas‐permeable polymer with enhanced selectivities is prepared using spirobifluorene as the main structural unit. The greater rigidity of this polymer of intrinsic microporosity (PIM‐SBF) facilitates gas permeability data that lie above the 2008 Robeson upper bound, which is the universal pe...

Summary:A highly gas‐permeable polymer with enhanced selectivities is prepared using spirobifluorene as the main structural unit. The greater rigidity of this polymer of intrinsic microporosity (PIM‐SBF) facilitates gas permeability data that lie above the 2008 Robeson upper bound, which is the universal performance indicator for polymer gas separation membranes.
