| Abstract: | Iodine capture is of great significance for disposal of the hazardous radioactive iodine. CTXP(O)Ph] , one kind of censer-shaped macrocycle cyclotrixylohydroquinoylene ( CTX ) derivatives, was applied as an efficient iodine adsorbent. It showed satisfactory iodine adsorption capacity in vapor phase and could be reused without obvious adsorption capacity loss. Besides, the adsorbent could also uptake iodine in water. Fortunately, two iodine loading CTXP(O)Ph] crystal structures were obtained under different conditions to explore the mechanism of iodine adsorption. This work provides a relatively rare example of iodine adsorption by macrocycle. It is promising that the results with crystal information might be meaningful for exploring and designing new kinds of iodine adsorbents. |
