Abstract This study reveals the mechanism of dual‐emission properties for asymmetrical diphenylsulfone and diphenylketone derivatives. A series derivatives with are designed synthesized. By single crystal structure analyses, various photophysical studies, 2D 1 H– H NOSEY NMR lower energy emission bands in spectra successfully assigned to hydrogen‐bonding‐assisted intermolecular charge transfer emission. The these compounds can easily be tuned both solid state solution by destroying or strengthening hydrogen bonding. In addition, thermally activated delayed fluorescence characteristics emissions also observed. control intramolecular transfers serves as basis generation white‐light For compound CPzPO, nearly pure CIE coordinates (0.31, 0.32) is achieved precipitation from dichloromethane hexane mixed solvent system. These results clearly give an insight into provide a rational strategy design synthesis single‐component white‐light‐emitting materials mechanoresponsive light‐emitting materials.
