Ultra-Microporous Triptycene-based Polyimide Membranes for High-Performance Gas Separation

A highly permeable and highly selective polyimide of intrinsic microporosity is prepared using a 9,10‐diisopropyl‐triptycene contortion center. The three‐dimensionality and shape‐persistence of triptycene afford exceptional sieving‐based gas separation performance transcending the latest permeabilit...

Summary:A highly permeable and highly selective polyimide of intrinsic microporosity is prepared using a 9,10‐diisopropyl‐triptycene contortion center. The three‐dimensionality and shape‐persistence of triptycene afford exceptional sieving‐based gas separation performance transcending the latest permeability/selectivity trade‐offs for industrial gas separations involving oxygen and hydrogen.
