Abstract: Organic porous materials, particularly metal organic frameworks(MOF) and covalent organic frameworks(COF), have emerged as a revolutionary class of materials with immense potential across a wide range of scientific and industrial applications. Their unique structural and functional properties, such as exceptional crystallinity, tunable porosity, and remarkable stability, have garnered significant attention in fields of adsorption separation, heterogeneous catalysis, energy storage, sensing, photoelectric conversion, and drug delivery. These materials are characterized by their highly ordered crystal structures and extensive conjugated systems, which not only enhance their mechanical and chemical stability but also make them highly compatible with ionizing radiation. This compatibility positions them as promising candidates for use in radioactive environments, where they can serve as efficient adsorbents or catalysts. Ionizing radiation technology, which includes gamma rays, X-rays, and electron beams, is particularly noteworthy for its strong penetration capabilities, mild processing conditions, operational simplicity, and scalability. These attributes make it an attractive tool for the preparation and modification of materials, including organic porous materials. Unlike conventional methods, which often require high temperatures, pressures, or toxic chemicals, ionizing radiation can induce chemical reactions and structural modifications under ambient conditions, thereby reducing the environmental impact and energy consumption associated with material synthesis. Furthermore, ionizing radiation is anticipated to emerge as an innovative energy supply method, paving the way for new catalytic systems. This review provides a comprehensive overview of organic porous materials, with a particular focus on MOF and COF materials, and traces their development history from their initial discovery to their current status as cutting-edge materials in various scientific disciplines. The discussion begins with an introduction to the fundamental properties of these materials, including their crystalline structures, porosity, and stability, and highlights the key factors that contribute to their combination with ionizing radiation. The review then delves into the latest research advancements in the radiation synthesis and modification of MOF and COF materials, exploring how ionizing radiation can be used to tailor their properties for specific applications. One of the most exciting areas of research in this field is the use of organic porous materials in radiation catalysis. Radiation catalysis involves the use of ionizing radiation to drive chemical reactions, often in the presence of a catalyst. Organic porous materials, with their high surface areas and tunable active sites, are ideal candidates for such applications. MOF materials have been shown to enhance the efficiency of radiation-induced reactions, such as hydrogen production in an aqueous system and the reduction of carbon dioxide to methanol, by providing a stable and highly reactive environment. The review highlights several case studies where organic porous materials have been successfully employed in radiation catalysis, demonstrating their potential to revolutionize this field. In summary, organic porous materials represent a new frontier in materials science, with the potential to transform a wide range of industries. Their unique properties, combined with their compatibility with ionizing radiation, make them ideal candidates for use in radiation chemistry and catalysis. As research in this field continues to advance, it is expected that these materials will play an increasingly important role in addressing some of the most pressing challenges in science and technology, from environmental remediation to energy storage and beyond.
