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. In this study, highly biocompatible phosphorescent nanoscintillators based hydrogen‐bonded frameworks (HOF) are designed engineered, termed BPT‐HOF@PEG, enhance in hepatocellular carcinoma (HCC) treatment. BPT‐HOF@PEG functions simultaneously as both scintillator photosensitizer, effectively absorbing transferring abundant . Both vitro vivo investigations demonstrate that internalized efficiently produces significant quantities of upon irradiation. Additionally, exposure directly inflicts DNA damage, the synergistic effects these mechanisms result pronounced cell death substantial tumor growth inhibition, with a inhibition rate up 90.4% assessments. RNA sequencing analyses reveal induces apoptosis Hepa1‐6 cells while inhibiting proliferation, culminating death. Therefore, work highlights considerable potential efficient HOF nanoscintillators‐based promising therapeutic approach HCC, providing effective alternative negligible patients unresectable

Abstract Stimuli‐responsive circularly polarized luminescence (CPL) materials have been attaching wide attention in the field of optical information storage and encryption, while still facing challenge realization high dissymmetry factors ( g lum ). This work presents a pair stimuli‐responsive chiral co‐assemblies P7R3 P7S3 by combining polymer PFIQ containing iso ‐quinoline units with inducers. The obtained can reversibly undergo significant modification CPL behavior under trifluoroacetic acid (TFA) fumigation annealing treatment, |g | values exhibiting reversible shift between 0.2 0.3. Moreover, before TFA fumigating effectively induce achiral emitters to generate intense full‐color signals through energy transfer (CPL‐ET), corresponding larger than 0.2. encryption decryption as well multi‐level logic gates application are achieved leveraging activity co‐assembly. provides new perspective for construction luminescent large activation emitters.

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. These interconvertible frameworks differ photothermal conversion performance selectively cause discoloration of CuSO 4 ·5H dehydration. Photothermal temperatures ultimately transformation framework, attaining up 640 K within 15 s under 808 nm laser irradiation (1.7 W cm −2 ).
