The influence of segmental chain motion on the gas separation performance of thermally rearranged (TR) polymer membranes is established for TR polybenzoxazoles featuring Tröger's base (TB) monomer subunits as exceptionally rigid sites of contortion along the polymer backbone. These polymers are accessed from solution‐processable ortho‐acetate functionalized polyimides, which are readily synthesized...
Gastrennungsmembranen …… verbinden ein starres Rückgrat mit hoher Porosität für eine gesteigerte Selektivität und Permeabilität. In ihrer Zuschrift auf S. 5006 berichten B. A. Helms et al. über die Synthese thermisch umgelagerter Polymermembranen mit starren gewinkelten Tröger‐Base‐Einheiten, die O2 und N2 sehr gut trennen. Die kleineren O2‐Moleküle “dringen durch die Ritzen” des starren porösen Polymergerüsts...
