Three dimensional porous triptycene network with 12-connectivity of tröger’s base for iodine capture

Developing new porous polymers with higher connectivity can improve their pore structure and increase functional group density, thereby enhancing their performance. Herein, we used tröger’s base (TB) groups as linkers to synthesize a novel 12-connected porous triptycene network (12-TB-PTN). The obtained 12-TB-PTN displayed high iodine capture capacity (515 wt %) and a relatively rapid adsorption rate (1.37 g h^-1) because of the high proportion of TB units in the porous polymer. This strategy has a great scientific importance for the development and preparation of rapid and efficient adsorbents for iodine vapor and other toxic pollutants.
