Abstract
Halogen bonding is an effective tool in solid-state supramolecular chemistry to stabilize crystal structures. In their Research Article (e202200236), Zhengxu Cai and co-workers introduced intermolecular halogen bonding (CN⋅⋅⋅Br) into a host—guest room-temperature phosphorescence (RTP) system, achieving fluorescence—phosphorescence dual emission. The weak intermolecular interactions of the halogen bond are sensitive to external stimuli (heat, mechanical force and X-rays), realizing colorimetric multi-stimuli response behavior.
