The treatment of radioactive iodine is particularly important and challenging because of its high ratio in fission product, extremely long radioactive periods up to several millions of years, as well as easy diffusion in the whole ecosystem. Given that several challenge including easy sublimation, high water solubility, diverse existing species of I₂, I⁻, I_2n+1⁻ and organic iodine, biocompatibility and strong aggregation in thyroid, rapid capture and permanent storage of iodine is requested. Comparing to inorganic adsorbents of zeolite and inorganic–organic hybrid MOFs, pure organic porous solid are emerging as new and promising iodine capture material. Their high iodine affinity and adsorption capacity, good stability in various environments, facile modification and functionalization, intrinsic structural flexibility guaranteed the outstanding performance in iodine capture. Four main categories of organic cages, supramolecular framework connected by weak interaction, covalent organic frameworks and polymers with intrinsic microporosity were summarized and discussed, from the viewpoints of design principles, iodine capture performance, and adsorbent-iodine interactions. As the main prospect, we hope this work will attracting more researchers to study porous organic materials and address the challenge of effective capture of radioactive iodine.</p></div>","PeriodicalId":638,"journal":{"name":"Journal of Inclusion Phenomena and Macrocyclic Chemistry","volume":"102 5-6","pages":"395 - 427"},"PeriodicalIF":2.3,"publicationDate":"2022-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10847-022-01128-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4892753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained compounds were characterized by a number of spectral methods confirming their structure and purity. Their base and acid ionization constants in the AN–HClO₄ and DMSO–potassium cryptate (KOH[222])—systems were measured by spectrophotometric titration. It was found that the asymmetric substitution architecture contributed to the stabilization of the protonated forms of porphyrins. This allowed, for the first time, to extract and spectrally characterize the mono- and doubly-protonated forms (H₃P⁺ and H₄P²⁺) of each ligands in the AN–HClO₄ system. The analysis of the spectral changes of the monoamino derivative led to identify three stages of the protonation, which first involves the nitrogen atom of the periphery substituent (p<i>K</i>_b = 13.26) and then the central nitrogen atoms of the macrocycle (p<i>K</i>_b1 = 11.50; p<i>K</i>_b2 = 9.65; p<i>K</i>_b1,2 = 21.15). The relative stability of the first intermediate is assumed to be caused by charge delocalization. The electron-donor nature of the solvent in the DMSO–KOH [222] system led to the leveling of the ionization constants for the first and second stages, which allowed us to determine only the total values for the porphyrins studied.

For the last decades, the NMR methods have been used to determine the physical and chemical properties of paramagnetic Ln compounds. The studies concerning paramagnetic NMR lanthanide-induced shifts (LISs) in dissolved Ln complexes, as well as the analysis of band shape as a function of temperature make it possible to obtain valuable information on the structure, intra- and intermolecular dynamics and paramagnetic properties thereof. This review is devoted solely to the following features: firstly, the processes of intramolecular dynamics of lanthanide complexes with polyamino-polycarboxylate ligands such as DOTA, EDTA and DTPA and their derivatives studied by NMR; secondly, the LISs of lanthanide complexes with EDTA, DOTA, DTPA and some of their derivatives depending on temperature and pH. Moreover, in this review, for the first time, the dependence of the activation energy of molecular dynamics in complexes with polydentate ligands on the atomic number of the lanthanide cation is analyzed and a monotonic change in energy is detected, which is due to the effect of lanthanide contraction. It should be noted that this phenomenon is quite general and may also appear in the future in many other series of lanthanide complexes with both other multidentate ligands and with bidentate and monodentate ligands. In the future, it is possible to predict the dependence of the properties of certain lanthanide complexes on the ionic radius of the lanthanide cation based on the approaches presented in the review. In this review, we have also presented the dynamic NMR as the main research method widely used to analyze the processes of molecular dynamics, and the structural studies based on the NMR relaxation spectroscopy and LIS analysis.</p></div>","PeriodicalId":638,"journal":{"name":"Journal of Inclusion Phenomena and Macrocyclic Chemistry","volume":"102 1-2","pages":"1 - 33"},"PeriodicalIF":2.3,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4473487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
