Synthesis of a Triazaisotruxene-Based Porous Organic Polymer and Its Application in Iodine Capture

A new triazaisotruxene-based porous organic polymer (POP) was designed and successfully synthesized by a FeCl3-promoted crosslinking reaction. As a result of its porosity and good thermal stability, the designed POP can be utilized as a promising adsorbent for iodine, not only in the gaseous phase, but also in organic and aqueous solutions. Compared to its triazatruxene (TN) analogue, the ITN-based POP shows equal iodine uptake in the gaseous phase and in hexane solution, and better uptake in aqueous solution.
