| 英文摘要 | Chiral materials have attracted considerable attention as emerging optical materials due to their distinct response to right and left circularly polarized luminescence (CPL). Designing multi-color CPL-active supramolecular nanomaterials with both high fluorescence quantum yields and large luminescence dissymmetry factors (g(lum)) remains a significant challenge. In our previous work, we successfully achieved chiral amplification by assembling chiral amino acid polymers with bis-crown ether macrocycles through host-guest interaction, forming supramolecular chiral helical complexes. However, these complexes emitted CPL only at a single wavelength, limiting their practical applications. To overcome this limitation, herein, we transformed the supramolecular organic chiral helical complexes into water-soluble nanoparticles with high aggregation-induced emission (AIE) property using a mini-emulsion strategy. By incorporating an achiral dye, 4,7-di(2-thienyl)-benzo[2,1,3]thiadiazole (DBT), as the relay acceptor and Nile red (NiR) as the final acceptor into the nanoparticles, excitation energy from the donor can be efficiently transferred to NiR via a two-step sequential F & ouml;rster resonance energy transfer (FRET) process, which significantly broadens the CPL emission spectrum. Notably, this system not only effectively transfers chiral information but also achieves multi-color CPL emissions, including high-quality white light emission, while demonstrating remarkable g(lum) values up to 10(-2) across a broad wavelength range. Our approach offers an innovative and convenient strategy for developing high-performance, multi-color tunable supramolecular CPL materials, providing insights for designing low-cost, multifunctional emitting devices. |
