Elemental halogen, that is fluorine (F2), chlorine (Cl2), bromine (Br2) and iodine (I2), plays an important role in the chemical industry. However, the toxicity, corrosiveness and volatility of elemental halogen pose serious challenges for their safe storage and transportation. Thus, the precuring of these elemental halogen can effectively improve the safety of their usage. Ideal precuring materials for elemental halogen need to meet a variety of requirements, such as stability, selectivity, recyclability, processability, etc., which brings great challenges to the design and synthesis of desired materials. So far, some precuring materials for Cl2 and Br2 have been reported (F2 is not available yet). The summary and review of these materials will help to provide reference for the follow-up materials optimization and design. However, as far as we know, the related review has not been reported yet. Therefore, we give a comprehensive overview of the precuring materials for Cl2 and Br2 including porous organic polymers (POPs), metal-organic frameworks (MOFs), porous organic cages (POCs) and metal halides. The corresponding mechanism and structure-property relationship are discussed in detail. The purpose of this paper is to provide a useful insight into the follow-up materials design for the elemental halogen precuring, and finally get an ideal precuring materials with practical application prospects, so as to improve the usage safety of elemental halogen and reduce the risk of halogen leakage. It is of great significance to environmental protection and sustainable development.
