摘要
手性碳点(Chiral carbon dots, CCDs)具有碳点独特的光电性质同时兼具手性特征,是一种具有较好发展前景的新兴纳米炭材料。水热炭化法制备CCDs包括基于手性传递策略的一步法和手性继承策略两步法,具有手性结构容易控制、光学性质可调、环境友好、水溶性优异的优点,在生物医学、传感、不对称催化、光电材料及复合材料领域中具有较好的应用效果,是目前应用最广泛的制备方法。本文综述了水热炭化制备CCDs的实验条件(原料种类、水热条件)对其手性特征、物理化学结构、光学性质和电学性质的影响,对CCDs应用进行了概述,对其未来发展进行了展望。
As an emerging carbon nanomaterial,chiral carbon dots(CCDs)have the unique photoelectric properties of carbon dots and chiral characteristics,which have good development prospects.The preparation of CCDs by hydrothermal carbonization includes a one-step method based on the chiral transfer strategy and a two-step method based on the chiral inheritance strategy,which exhibited the advantages of easy control of chiral structure,adjustable optical properties,environmental friendliness and excellent water solubility.It has good application effects in the fields of biomedicine,sensing,asymmetric catalysis,optoelectronic materials and composites,and is the most widely used preparation method at present.In this paper,the effects of experimental conditions(source types,hydrothermal conditions)on the chiral characteristics,physical chemical structure,optical properties and electrical properties of CCDs prepared by hydrothermal carbonization are reviewed.The applications of chiral carbon dots are summarized and their future developments are prospected.
