Coumarin‐based fluorescent sensors

Abstract

The application of coumarin probes as chemosensors for the detection of various species has been broadly explored in recent ages because of their exclusive optical photophysical presentation. The present review especially emphasizes the mechanism involved in the recognition of various vital species through coumarin probes and highlights the current developments in the design of such types of coumarin chemosensors. We also draw attention to the application of the concern protocol and shortfalls of reported coumarin‐based fluorescent probes and express our standpoint on future progress in this arena. We are optimistic that the present review can be explored not only as a reference guide for novices but conjointly as a compass of these fields and contribute to cracking more brilliant and meaningful moieties for biological and chemical researchers.
