Abstract

Large-scale optically active nanomaterials have attracted increasing attention due to their enhanced chiral optical responses. Compared with traditional nanoscale chiral systems, these large-scale structures can exhibit stronger circular dichroism and circularly polarized luminescence through effects such as collective resonance and near-field coupling. In recent years, significant progress has been made in this field, enabling the controlled synthesis of large-scale chiral nanomaterials and thereby opening up significant opportunities for their application in novel optical devices and functional materials.

This review systematically summarizes the latest advances in large-scale optically active nanomaterials, covering synthesis strategies, optical tuning, and application areas. We also delve into the intrinsic mechanisms underlying their chiral optical activity and analyze the correlations between structural parameters and optical responses. Finally, this review looks ahead to the major challenges currently facing the field and future directions for development. Despite significant breakthroughs, critical issues remain to be addressed, such as establishing quantitative models linking structural parameters to chiral optical properties, achieving precise structural control, and developing large-scale synthesis capabilities.

Optically active nanomaterials offer unique applications in photovoltaic energy conversion, multiphase catalysis, and biomedical diagnostics. To overcome the limitations imposed by scale effects on material properties, researchers have developed large-scale chiral nanomaterials with dynamic tunability, enabling targeted optimization of material characteristics. With chiral structural parameters kept constant, chiral structures that reach at least the 2 × 10⁻⁷ m scale significantly enhance optical activity, enabling applications in electronic spin, catalysis, bioseparation, and sensing, as well as medical diagnosis and therapy. Therefore, this paper provides a comprehensive overview of research progress in large-scale optically active nanomaterials and an in-depth discussion of three key aspects: preparation strategies, structure-property modulation, and applications. Through a thorough analysis of and outlook on the advancements in large-scale optically active nanomaterials, this paper aims to establish a solid theoretical foundation and practical pathways for the design and industrial application of next-generation functional materials.

大尺度光学活性纳米材料：合成、结构调制和功能集成

光活性纳米材料在光伏能量转换、多相催化和生物医学诊断方面提供了独特的应用。为了克服尺度效应对材料性能的限制，研究人员开发了具有动态可调性的大规模手性纳米材料，实现了材料特性的定向优化。在保持手性结构参数不变的情况下，至少达到2 × 10−7 m尺度的手性结构可显著增强其旋光性，从而在电子自旋、催化、生物分离、传感以及医学诊断和治疗等方面得到应用。因此，本文综述了大规模光活性纳米材料的研究进展，并从制备策略、结构-性质调制和应用三个关键方面进行了深入讨论。本文通过对大规模光活性纳米材料研究进展的深入分析和展望，旨在为下一代功能材料的设计和产业化应用奠定坚实的理论基础和实践途径。
