The article describes a series of new organic crystals of various structures and draws conclusions about their structure (strong network of hydrogen bonds, the possibility of chemical crosslinking of molecules into a polymer network, and porosity) and suggests ways to tune the required properties. Among these properties is high order, insolubility, large capacity for absorption of the solvent and iodine molecules with reversible swelling and an increase in the volume of the crystal. The new porous materials created on the basis of the described structures will help to improve the filtration of water from polluting substances. In particular, from stable and radioactive isotopes of iodine, which will greatly facilitate the elimination of the consequences of industrial disasters, such as the accident at the Fukushima-1 nuclear power plant. Further, the materials will find applications in the production of filtering devices, both in industry and in everyday life.
