Organic phosphors integrating circularly polarized persistent luminescence (CPPL) across the visible range are widespread for applications in optical information encryption, bioimaging, and 3D display, but pursuit of color-tunable CPPL single-component organics remains a formidable task. Herein, via situ photoimplanting radical ion pairing into axial chiral crystals, we present elucidate an unprecedented double-module decay strategy to achieve colorful through combination stable triplet emission from neutral diphosphine doublet radiance photogenic radicals exclusive crystalline framework. Owing photoactivation-dependent component inherent phosphorescence asymmetric environment, CPL vision can be regulated by altering photoactivation observation time window, allowing glow tuning blue orange delayed green emission.

Abstract Metal halide perovskites (MHPs) are commonly used in polarization‐sensitive photodetectors (PDs) for applications such as polarization imaging, remote sensing, and optical communication. Although various methods exist to adjust the photocurrent, a universal effective approach continuous control of MHPs’ optoelectronic polarized properties is lacking.

Abstract Circularly polarized luminescence (CPL) is promising for applications in many fields. However, most systems involving CPL are within the visible range; near‐infrared (NIR) CPL‐active materials, especially those that exhibit high g lum values and can be controlled spatially temporally, rare. Herein, dynamic NIR‐CPL with a value of 2.5×10 −2 was achieved through supramolecular coassembly energy‐transfer strategies. The chiral assemblies formed by between adenosine triphosphate (ATP) pyrene derivative exhibited red signal ( 10 −3 ). further introduction sulfo‐cyanine5 resulted process, which not only led to NIR but also increased . Temporal control these realized introducing alkaline phosphatase fabricate biomimetic enzyme‐catalyzed network, allowing turned on.

Abstract Circularly polarized light (CPL)‐responsive artificial synaptic devices are of significant interest for advanced neuromorphic visual systems, as they enhance perceptual capabilities and enable the development novel applications. Nevertheless, progress in this field is hindered by lack suitable CPL‐active organic semiconductor materials. In study, environmentally friendly cellulose nanocrystals (CNCs) with a chiral helical structure dielectric layer to realize CPL‐resolved behaviors transistors utilized. The device exhibits much stronger response right‐handed CPL (RCPL) than left‐handed (LCPL) because CNCs reflects LCPL while transmitting RCPL. By modulating electrical optical signals, successfully simulates multiple activities, including plasticity, CPL‐dependent brain‐like learning memory behavior controlled photoelectric cooperative stimulation. Additionally, demonstrates applications blue‐light‐induced fatigue simulation, recognition, wireless encrypted communication.
