Transcription of Customized Circularly Polarized Luminescence from Enantiomeric Metal–Organic Framework to Carbon Dots

Abstract Chiral carbon dots (CDs) with circularly polarized luminescence (CPL) are one of the most dynamic areas of modern science. However, the design, preparation, and ambiguity mechanism of solid‐state CPL‐active CDs remains a formidable challenge. Herein, for the first time, CDs with customized chiroptical activities in the solid state, especially CPL, are transcribed from chiral metal–organic framework (CMOFs) via a bottle‐around‐ship strategy. Within these CMOFs⊃CDs assemblies, CDs inherited the chirality of the host CMOFs through host–guest interactions, which is revealed by density functional theory (DFT) simulations and experimental results, and amplified the luminescence dissymmetry factor ( g lum ) by effective artificial chiral light‐harvesting systems. Impressively, CMOFs⊃CDs in pairs generated color‐tunable CPL and white CPL with chromaticity coordinates of (0.32, 0.32). Furthermore, benefiting from excellent processability, as luminescent coatings and 3D printing inks, a white circularly polarized light‐emitting diode, and an extended 3D model “light bulb” featuring white CPL are successfully fabricated, respectively. This strategy paves a new avenue for the synthesis and advanced application of solid‐state CPL‐active CDs‐based materials.
