Halogen Bonding Regulated Functional Nanomaterials

Non-covalent interactions have gained increasing attention for the use as a driving force to fabricate various supramolecular architectures, exhibiting great potential in crystal and materials engineering and supramolecular chemistry. As one of the most powerful non-covalent bonds, halogen bond recently received increasing attention in functional nanomaterials design. The present review describes the latest studies based on the halogen bonding induced self-assemblies and their applications. Due to the high directionality and controllable interaction strength, halogen bonding can provide a facile platform for the design and architecture of myriad of nanomaterials. In addition, both the fundamental aspects and the real engineering applications are discussed, which encompass molecular recognition and sensing, organocatalysis, and controllable multifunctional materials and surfaces.
