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

Abstract X‐ray induced photodynamic therapy (X‐PDT) leverages penetrating to generate singlet oxygen ( 1 O 2 ) for treating deep‐seated tumors. However, conventional X‐PDT typically relies on heavy metal inorganic scintillators and organic photosensitizers produce , which presents challenges related toxicity energy conversion efficiency.

Abstract Stimuli‐responsive programmable materials exhibit remarkable potential for smart applications due to their ability attain multi‐stable states through structural adaptability upon guest molecule removal or exchange. However, achieving designability remains challenging, particularly in maintaining the crystallinity single‐crystal‐to‐single‐crystal (SCSC) transformations and ensuring tunable activation. In this study, it is demonstrated that SCSC between an empty monoclinic framework triclinic can be manipulated stimuli combining various activations molecules. Reversible switching facilitated by MeOH adsorption heating‐induced transformations, whereas H 2 O alone cannot directly induce transformation. Instead, must first adsorb N,N ‐Dimethylformamide (DMF) molecules form a new DMF‐adsorbed subsequently undergoes mild activation yield framework.
