Halogen bonding in supramolecular chemistry: From molecular components to assembled structures

Abstract

Halogen bonding, one of the important driving forces for molecular assemblies, plays a significant role in supramolecular chemistry due to its stability, tunability, and directionality. In recent years, supramolecular structures driven by halogen bonding have been rapidly developed at the theoretical and practical levels, and their potential for application in sensing, detection, optical engineering, and anion recognition has been expanded. In this review, we focus on halogen bond-assisted molecular components and assembled structures and conduct an in-depth analysis of the latest practical applications of halogen bond-directed functional assemblies. Finally, we discuss the future development trends and challenges of the assemblies driven by halogen bonding as new functional materials. This review summarizes and analyzes current research accomplishments, providing a theoretical foundation and practical guidance for designing supramolecular assembly materials driven by halogen bonding.
