“…Halogen bonding is an intermolecular interaction that forms between sigma-hole of halogen atoms and Lewis-bases such as oxygen, nitrogen, sulfur, or π electron. , It was first reported in 1863, and its similarity to hydrogen bonding has long been discussed due to the comparable behavior of halogen and hydrogen as electron donors . Despite the extensive incorporation of hydrogen bonding into polymeric structures for various applications such as self-assembling, self-healing, and shape-memory materials, the integration of halogen bonding into polymers remains almost unexplored. , In fact, the research related to halogen-bonded polymers has been almost limited to synthesis or physical behavior, while there have been few attempts to develop multifunctional halogen bonded polymers especially for medical purposes and other applications. Moreover, the introduction of halogen bonding into polymers has mainly relied on donor–acceptor pair systems or small molecule additives .…”
