UV‐Curing‐Enhanced Organic Long‐Persistent Luminescence Materials

Abstract Amorphous organic long‐persistent luminescence materials (OLPLMs) can realize simpler solution processing and large‐area uniform luminescence, where the luminescent properties are significantly influenced by the rigid environment. However, research on utilizing the rigidity to promote long‐persistent luminescence (LPL) properties of amorphous OLPLMs is still relatively rare due to the lack of an unambiguous and effective strategy to construct the rigid environment. Here, a universal strategy is proposed to enhance the LPL performance of organic host–guest doping systems by UV curing, which utilizes the rigid environment constructed by UV curing to promote the interaction between host and guest, thus inducing a generation of materials with highly efficient LPL performance. This solution‐processable, large‐area, and “easy‐to‐realize” material fabrication strategy can make amorphous OLPLMs show broader application prospects in some fields, such as anti‐counterfeiting, nondestructive detection, and pattern marking or indication.
