有机近红外电致发光材料研究进展

摘要

近红外发光材料是一类发光波长介于700～2500nm的光电功能材料,在光纤通讯、传感、生物活体检测和医学成像等领域具有广阔的应用前景.介绍了有机近红外电致发光材料的分类,小分子近红外电致发光材料、聚合物近红外电致发光材料以及过渡金属配合物近红外电致发光材料的发展现状,指出了发光光谱和发光效率调控途径,阐述了有机近红外电致发光材料的发展前景.%Near-infrared (NIR)emitting materials are a class of photo electronic functional materials, which transmit electromagnetic radiation with an emissive wavelength extending from 700nm to 2500 nm.They have attracted much more attention because of their potential applications in optical fiber communication,sensing,biological living detection and medical imaging,etc.The classification and their state of the art of near-infrared (NIR)organic electroluminescent materials of small molecules, polymers and transition metal complexes are introduced in this paper.The approaches to adminstrate luminescence spectra and luminous efficiency about near-infrared materials are presented.The develop-ment prospect of organic near-infrared electroluminescent materials is prodicted.
