摘　　要：发展环境水样和生物体内各种金属离子、阴离子的定量检测方法对于避免离子中毒事故和研究金属离子的生物活性具有重要意义。香豆素类染料分子化学性质稳定,光物理性能优秀,非常适合用于开发具有离子识别能力的荧光传感体系。本文围绕香豆素分子的结构设计,从“能够识别多种离子的香豆素探针分子”和“基于香豆素染料分子的金属离子阵列传感器”2个研究方向,讨论了香豆素荧光染料探针分子在同步识别多种金属离子和阴离子应用领域的研究进展。可以看出,无论是开发具有多个识别位点的特异性探针分子,还是基于模式识别原理的阵列传感器,香豆素类染料分子在多种离子识别领域均展现出光明的应用前景。The development of analytical methods for quantitative detection of various metal ions and anions in both environmental water samples and living organisms was meaningful to avoid poisoning events and investigate the biological roles of important ions.In this regard,coumarin dyes were chemically stable,easy to be synthesized and modified,and exhibited excellent photophysical properties.Therefore,they were suitable for developing fluorescent sensing systems with ion recognition capabilities.In this review,we focused on the structural design of coumarin-based dye molecules for simultaneous recognition of multiple target ions.Research progresses on fluorescent sensors and sensor arrays based on coumarin dye molecules for high-throughput detection and discrimination of multiple target metal ions and anions were discussed with representative examples.It could be discovered that coumarin dye molecules indeed had good application prospects either as a probe molecule with multiple recognition sites,or a sensor array based on pattern recognition.
