外文摘要：Segregation of radioiodine species is critical for nuclear safety, and adsorption-based capture has shown great promise for the remediation of pollutants. In this study, a series of isostructural hydrogen-bonded organic frameworks (HOFs) with various polarities were fabricated. The optimal material, HOF-TAM-BPY, exhibited I-2 uptake capacities of 783 wt% and 112 wt% from the air and aqueous solution, respectively, placing it among the top reported systems. HOF-TAM-BPY also exhibited fast adsorption kinetics, full recyclability, and outstanding moisture tolerance. The promoting effect of the pyridine moieties and the unique pore structure of HOFs on the I-2 adsorption was comprehensively elucidated by spectrally identifying the hosted iodine species and calculating the host-guest interactions. These results demonstrate the essential role of the pore environment of the adsorbent in achieving high iodine capture performance.
