Halogen bonding in room-temperature phosphorescent materials

Abstract Room-temperature phosphorescent materials have recently attracted much research interest due to their unique physicochemical properties and potential applications in many areas. Noncovalent interactions play key roles in design, preparation and application of new and highly efficient room-temperature phosphorescent materials. In this review, the important roles of halogen bonding, one of the fundamental noncovalent interactions, in enhancing room-temperature phosphorescence are outlined based on recent progresses in both experimental and theoretical studies on this topic. Brightened prospects for future design, preparation and application of room-temperature phosphorescent materials by utilization of halogen bonding are also briefly discussed.
