摘　　要：聚合物点由于具有易调控的光电特性一直备受相关领域研究者们的关注。作为一种新型碳基纳米材料,聚合物点的分类、合成方法及性能仍缺乏较为系统的总结。本篇综述根据聚合物点的结构,将其分为共轭聚合物点和碳化聚合物点,主要围绕两种聚合物点的定义、合成方法及发光机理进行了讨论。此外,本文还对聚合物点近年来的光学应用进行了总结,包括生物成像和荧光标记、药物和基因传递、传感、光电器件、光催化和防伪等。Polymer dots(PDs)have attracted intensive attention due to their advantages of tunable electrical and optical properties based on suitable manipulation of the structure and composition.As a new type of dots,the classification,synthetic methods and properties of PDs still lack systemic summarization.In this review,the polymer dots are divided into two kinds based on their structures:conjugated polymer dots(CPDs)and carbonized polymer dots(carbonized PDs).The definitions,synthetic methods and photoluminescence mechanisms of the two PDs will be discussed.Besides,their applications are demonstrated including bioimaging and fluorescent labelling,drug and gene delivery,sensing,photocatalysis and anti-counterfeiting.
