摘　　要：共价有机框架(COFs)材料是由有机结构单元通过共价键在原子水平上精确连接形成的周期性多孔材料,具有结晶性好、密度低、比表面积高和结构可设计等优点,在荧光分析检测领域展现出巨大的应用潜力,已引起科研工作者的广泛关注。本文讨论了COFs的结构和荧光性能之间的关系,重点介绍了近年二维COFs在爆炸物、有机污染物、金属离子和pH值等的分析检测中的研究和应用进展,对基于COFs的荧光传感器面临的挑战进行了分析,并对未来的发展方向进行了展望。As a newly emerging kind of periodic porous material,covalent organic frameworks(COFs)are precisely connected at atomic level through covalent bonds.COFs have drawn much attention because of their fascinating structural features(e.g.,large specific surface area,high porosity and crystallinity,low density,designable structure),showing wide potential applications in fluorescence detection field.In this paper,the relationship between the structure and fluorescence properties of COFs was overviewed,and the current research advances of two-dimensional COFs in fluorescence detection such as explosives,other organic pollutants,metal ions and pH were summarized.Finally,the opportunities and challenges in fluorescence sensor constructed by COFs were discussed.
