Abstract :
A series of star triptycene-based porous polymers (STPs) were synthesized from the palladium-catalyzed C–C coupling polymerization of 2, 6, 14-triiodotriptycene. The porous properties of these STPs including surface area, pore size and gas adsorption can be tuned by varying the strut length from ethynylene to phenylene to phenyleneethynylene. As STP-5, they display the BET surface area of 601 m2 g−1, and exhibit excellent adsorption ability to hydrogen (1.0 wt% at 1.0 bar/77 K) and carbon dioxide (9.4 wt% at 1.0 bar/273 K).
