Abstract Chiral metallacages, with their precisely distributed luminescent and chiral units inherent adaptive chirality, represent an ideal framework for developing circularly polarized luminescence (CPL)‐active materials. Despite potential, enhancing the dissymmetry factor ( g lum ) of metallacage‐based materials remains a significant challenge. In this study, useful approach is proposed by co‐assembling donor metallacage Δ 4 / Λ ‐Zn A achiral acceptor Nile red (NiR), achieving efficient energy chirality transfer resulting in enhanced CPL these co‐assemblies. More importantly, microfluidic laminar flow utilized, known providing stable driving forces confined spaces, to achieve marked improvement values co‐assemblies within polymethyl methacrylate (PMMA) films. Computational fluid dynamics (CFD) simulations small‐angle X‐ray scattering (SAXS) experiments confirm that films containing /NiR, prepared via chips, display well‐defined distributions metallacages NiR due controllable assembly process facilitated flow. This work pioneers new methodology significantly enhance materials, opening avenues field photonics.

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. Based on enzyme‐regulated temporally controllable assemblies, multilevel information encryption system developed. This study provides pioneering example construction materials ability perform temporal via assembly strategy, expected aid design complex more closely resemble natural biological systems.
