Abstract: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.
