Abstract

The adsorption of iodine by porous organic polymers is an active research topic. Here, we synthesized three porous organic polymers, TTDP-1, TTDP-2, and TTDP-3, to study the adsorption of iodine. A suitable configuration for iodine adsorption was identified by flexibly adjusting the stacking degree of aldehyde monomers to change the porosity of the porous organic polymer. The adsorption power of TTDP-1, TTDP-2, and TTDP-3 to iodine can reach 536, 470, and 425 wt %, respectively. All exhibit good adsorption capacity. By studying the thermogravimetric and infrared spectra of the TTDP-X material before and after iodine adsorption, we proved that iodine can form a charge transfer complex between the aromatic skeleton connected by the imine bond. This combination can increase iodine adsorption.
