Polyimide (PI)-based gas separation membranes are of great interest in the field H2 purification owing to their good thermal stability, chemical and mechanical properties. Among polyimide-based membranes, intrinsically microporous polyimides easily soluble common organic solvents, showing potential for fabricating hollow fiber membranes. However, based on solution-diffusion model, improving free volume or movability polymer chains can improve permeability, but would result poor stability. Herein, we develop a carbazole-alkyl-based diamine monomer that endows PI with "rigid-soft" structure balance trade-off between them. Soft units enhance during film-forming process, ensuring rigid achieve tight chain packing strong intermolecular interactions. Meanwhile, bulky carbazole groups could further restrict motion soft solid state. On one hand, it restricts below Tg, enhancing small selectivity He. other ensures Moreover, extending length alkyl helps interactions simultaneously, thereby optimizing permeability/selectivity trade-off. As result, as-prepared shows permeability 89.61 Barrer, H2/CH4 87.85, H2/N2 45.03 contrast reference FPI TFMB-6FDA exhibiting 92.95 72.62, 38.57. high Tg value 334 °C is also achieved.
