Abstract

A three-dimensional rigid "six-connected" porous triptycene network based on Tröger's base (TB-PTN) was synthesized by using triptycenes as connectors and Tröger's base as linkers. With characteristics of a high surface area of 1528 m² g^-1, nitrogen-enriched groups, and superior thermal stability, TB-PTN displays a high CO₂ uptake of 22.3 wt % (273 K, 1 bar) and excellent iodine vapor adsorption (240 wt %).

Keywords: CO2 capture; Tröger’s base; iodine enrichment; microporous organic polymers; triptycene.
