Abstract: Four kinds of triptycene-based polyimides networks with intrinsic microporosity (Trip-PIMs) were synthesized through one-step solution condensation of triaminotriptycene and 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA), pyromellitic dianhydride (PMDA), 3,3’,4,4’-biphthalic anhydride (BPDA) and spirobisindane-linked dianhydride (SBIDA). The microporous structure and properties of the four polyimides were characterized by FI-IR, solid-state 13C-NMR， SEM, TG and N2 adsorption. The sorption capability for organic gases and liquids were tested. Results show that the introducing of triptycene makes the polyimides obtain high Brunner-Emmet-Teller surface areas. Meanwhile, they have a good swelling property. Compared with the alkane, the sorption capabilities of the four polyimides to anime and benzene are better. Distorted structure in the networks makes the porous skeleton easier to swell and dramatically enhances the sorption capability.
