摘　　要：金纳米团簇(金簇)凭借其丰富的光学性能和独特的纳米结构在催化、生物成像、传感、分析检测、药物传送、显示和照明等领域脱颖而出。然而,较低的量子产率和单一的发光波段严重阻碍了金簇的发展前景,制备可调谐、高量子产率、长寿命的金簇已成为目前该领域的研究重点。主客体包结、嵌入聚合物基质以及氢键、静电作用力等超分子策略已被广泛用于调控金簇的发光行为,有效地提高金簇发光量子产率。鉴于此,系统阐述了超分子策略调控金簇发光行为的机理,总结了近年来基于超分子策略构建及调控多功能金簇发光行为的研究进展,并展望了金簇发光领域面临的机遇与挑战。Au nanoclusters(AuNCs) stand out in the fields of catalysis,bioimaging,sensing,analytical detection,drug delivery,displaying and illumination owing to their abundant optical properties and unique nanostructures.However,the low quantum yield(QY) and single emissive band seriously hinder the development prospects of most AuNCs,and the preparation of AuNCs with tunable luminescence,high QY,and long luminescent lifetime has become current research focus in this field.Supramolecular strategies such as host-guest inclusion,embedding in polymer matrix,hydrogen bonding and electrostatic interactions have been widely used to control the luminescent behavior of AuNCs and improve their QY.In view of this,this review systematically expounds the mechanism of supramolecular strategies to modulate the luminescent behavior of AuNCs,summarizes the recent research progress in the construction and regulation of multifunctional AuNCs based on supramolecular strategies,and looks forward to the opportunities and challenges in the field of AuNC luminescence.
