摘　　要：近年来,随着碳点在合成路线、反应机理、光学性质等方面的发展,大量的工作聚焦于红光或近红外光等长波长发射的碳点。长波长是指发射范围在600~1800 nm的红色或近红外光谱区,相比短波长碳点,其具有深组织穿透、较小自荧光、长荧光寿命以及光损伤小等特点,能够进一步应用在生物医学治疗、光电子以及光学器件制备等领域。因此,深入探究长波长发射碳点的设计和合成对于其发展和广泛应用具有重要意义。本文综述了近年来长波长发射碳点的研究进展,从碳源选择和光学性质调控两个方面介绍了长波长发射碳点的设计与制备。选择氨基较多的脂肪族化合物和具有共轭结构的芳香化合物,以及通过调控有效共轭长度、表面修饰和杂原子掺杂等方法来调控其光学性质。最后,阐述了长波长碳点在生物医学、LED光学器件和加密防伪等一些领域的最新研究和未来的挑战。In recent years,with the development of carbon dots in terms of synthesis routes,reaction mechanisms,and optical properties,a large amount of work has focused on carbon dots that emit long wavelengths such as infrared or near-infrared.Long wavelength refers to the red or near-infrared spectral region whose emission range is 600-1800 nm.Compared with short-wavelength carbon dots,they have the characteristics of deep tissue penetration,less autofluorescence,long fluorescence lifetime and less light damage,and can be further applied in the fields of biomedical treatment,optoelectronics and optical device preparation.Therefore,in-depth exploration of the design and synthesis of long-wavelength emitting carbon dots is of great significance for their development and wide application.This article reviews the research progress of long-wavelength carbon dots in recent years,and introduces how to prepare long-wavelength carbon dots from two aspects:carbon source selection and control of optical properties.For example,choose some aliphatic compounds containing more amino groups and aromatic compounds with conjugated structures.And its optical properties can be controlled through changing the effective conjugation length,surface modification,and heteroatom doping.Finally,the latest research and future challenges of long-wavelength carbon dots in some fields such as biomedicine,LED optics,encryption and anti-counterfeiting are introduced.
