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.

Counterintuitively, the with higher causing even greater deceleration. This phenomenon is observed both photo- thermally activated cyclic reactions. Molecular dynamics simulations confocal laser scanning microscopy suggest aliphatic chains grafted onto nanowires interact anisotropic molecules, increasing their local concentrations near nanowires. Notably, azobenzene photoisomerization completely inhibited dispersion, despite completing within 30 s absence We propose align reactive molecules directionally, confined space prevents bulky cis-isomer formation.
