随着全球经济的快速发展，传统能源已经不能满足人类的需求。作为一类新型能量，核能目前发挥着重大的作用。然而随着核能的快速发展，大量的挥发性放射核素被释放到大气中。其中放射性碘因对人体的代谢系统有着严重的影响而备受人们的关注。目前用来吸附碘的材料主要为多孔材料，如金属有机框架材料，共价有机孔架材料等等。在此论文中，我们报道了一种单组分非孔有机化合物晶体对碘的吸附性能的研究。同时，在该单组分有机晶体吸附水溶液中碘的过程中，发生了由氢键诱导的单晶到复合晶体的转变。

With the rapid development of the global economy, traditional energy sources can no longer meet human needs. As a new type of energy, nuclear energy currently plays a major role. However, with the rapid development of nuclear energy, a large amount of volatile radionuclides is released into the atmosphere. Among them, radioactive iodine has attracted people's attention because of its serious impact on the human metabolic system. At present, the main materials used to adsorb iodine have porous structure, such as metal organic framework materials (MOFs), covalent organic pore framework materials (COFs) and so on. In this paper, we report the adsorption of iodine by a single-component nonporous organic crystal. At the same time, during the adsorption of iodine in the aqueous solution by the single-component organic crystal, a hydrogen-induced single crystal to cocrystal transition occurred.
