Coumarin-Based Fluorescent Sensors

Fluorescent sensors can transfer molecular recognition events into fluorescent signals. Of the various kinds of chemosensors, fluorescent sensors offer distinct advantages in terms of sensitivity, selectivity, response time and in situ observation. Monitoring in real-time and real-space the level of analytes is of great interest to many scientists, including chemists, biologists, clinical biochemists and environmentalists. Fluorescent sensors based on coumarin have drawn much attention in recent years . In this paper, the molecular design, mechanism and application of coumarin-based fluorescent sensors for cations, anions and neutral molecules are reviewed. The developing orientation for further research is presented.
