“…At present, the rapid preparation of host–guest doped crystals mainly relies on host molecules that are easy to crystallize. 25,26 Meanwhile, the host molecule can isolate oxygen and restrict non-radiative transitions of excited state electrons, playing an important role in constructing host–guest doping systems. 27,28 Common host molecules with good crystallinity include diphenylamine, 29 triphenylamine, 30 and triphenylphosphine.…”

Circularly polarized luminescence (CPL) materials offer exciting potential due to their unique light properties. However, controlling the color of afterglow emission, a key feature for many applications remains a challenge. Here, a co‐doping strategy is presented for precise control of multicolor CPL afterglow in films. This approach utilizes chiral naphthylphosphoric acid derivatives as energy and chirality transfer donors, commonly used fluorescent dye rhodamine B (RB) and PVA are selected as the acceptor and the polymeric matrix, respectively. Remarkably, the co‐doped films exhibit ultra‐long green circular polarization phosphorescence lasting several seconds with high efficiency (14.23%), lifetime (1025.5 ms), and dissymmetry factor (8.44 × 10−3). Crucially, by adjusting the acceptor content, it can precisely tune the phosphorescence‐to‐fluorescence ratio and achieve multicolor afterglow. This control stems from a combination of Förster resonance energy transfer, chirality transfer, and color‐mixing effects. Furthermore, this approach significantly improves the asymmetry factor of the CPL afterglow by an order of magnitude (5.17 × 10−2). It is anticipated that this straightforward approach to precisely regulating the afterglow color of CPL will provide invaluable insights for the future design of highly efficient and innovative CPL materials.

Amorphous organic long‐persistent luminescence materials (OLPLMs) can realize simpler solution processing and large‐area uniform luminescence, which 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, we propose a universal strategy 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 the generation of 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, non‐destructive detection, and pattern marking or indication.This article is protected by copyright.
