Abstract :
A series of triptycene-based porous polyimides (STPIs) were synthesized by condensation polymerizations. The structure and properties of these STPIs were characterized by IR, solid 13C NMR, powder XRD, SEM, TEM and gas absorption. As STPI-2 with the high thermal stability, they display excellent adsorption ability to CO2 uptake capacity of 14.6 wt% (273 K), and exhibit the high selectivity of CO2/N2 of 107.
