Abstract
A highly gas permeable polymer with exceptional size selectivity is prepared by fusing triptycene units together via a polymerization reaction involving Tröger's base formation. The extreme rigidity of this polymer of intrinsic microporosity (PIM-Trip-TB) facilitates gas permeability data that lie well above the benchmark 2008 Robeson upper bounds for the important O 2/N2 and H2/N2 gas pairs. © 2014 WILEY-VCH Verlag GmbH & Co.
