| Abstract | We report a side group modification strategy to tailor the structure of a polymer of intrinsic microporosity (PIM₋₁). PIM₋₁ with an average of ∼50% of the repeat units converted to tetrazole is prepared, and a subsequent reaction then introduces three types of pseudo-ionic liquid tetrazole-like structures (PIM₋₁-ILₓ). The presence of pseudo-ionic liquid functional groups in the PIM₋₁ structure increases gas selectivities for O₂/N₂ and CO₂/N₂, while it decreases pure-gas permeabilities. The overall gas separation performance of PIM₋₁-ILₓ is close to the 2008 Robeson upper bound. Since the tetrazoles are versatile groups for building a wide variety of ionic liquids, the modification method can be expanded to explore a broad spectrum of functional groups. |
