Organic framework materials have garnered significant attention due to their customizable porous structures and diverse functionalities.The mode of connection among organic motifs plays a pivotal role in shaping the inherent characteristics and properties of these frameworks,thereby exerting a substantial influence on their overall functionality.In recent times,there has been a growing interest in organic frameworks built upon halogen bonds,owing to their distinctive attributes.Compared with the traditional halogen bond,the[N…I+… N]halogen bond has higher bond energy,and the organic frameworks constructed based on these halogen bonds are more stable,and have unique and rich properties and application prospects in adsorption and separation,magnetism,reaction and other fields.This review introduced two types of halogen-bonded organic frameworks:those based on traditional halogen bonds and those founded on the[D…X+…D]halogen bonds.It not only introduces these frameworks but also provides a comprehensive overview of their properties and functionalities.Additionally,the potential development for[D…X+…D]halogen-bond organic frameworks is outlined,highlighting the promising avenues for future research and application.
