摘　　要：罗丹明是以氧杂蒽为母体的碱性呫吨染料,因其优良的光学性能如吸收系数大、光稳定性好和荧光量子产率高等,常常被选作荧光母体用于金属离子荧光探针的设计和制备。主要对罗丹明类荧光探针在铜离子、汞离子、铁离子检测中的应用进行归纳总结,对其结构特征、作用机理、检测水平和应用范围等进行了详细的比较分析。最后,提出了此类荧光探针目前存在的问题和今后的发展趋势。As one kind of the xanthenes,rhodamine is often selected as the mother molecule for the design and synthesis of the metal ion fluorescent probe because of its excellent optical properties such as large absorption coefficient,good light stability and high fluorescence quantum yield. The applications of rhodamine fluorescent probes in the analysis of copper ion,mercury ion and iron ion are summarized. A detailed comparative analysis of its features including structure,response mechanism,corresponding detection level and scope of application is carried out. In addition,the existing problems and future development trends of this kind of fluorescent probes have been discussed.
