Porous Triptycene Network Based on Tro''ger's Base for CO₂ Capture and Iodine Enrichment

A three-dimensional rigid "six-connected"poroustriptycene network based on Tro''ger's base (TB-PTN) wassynthesized by using triptycenes as connectors and Tro''ger'sbase as linkers. With characteristics of a high surface area of 1528m(2) g(-1), nitrogen-enriched groups, andsuperior thermal stability, TB-PTN displays a high CO2 uptakeof 22.3 wt % (273 K, 1 bar) and excellent iodine vapor adsorption(240 wt %).
