Two novel coumarin-based fluorescent probes for the detection of Cu2+ and biological applications

“…Coumarin dyes are widely used in fluorescent probes because of their low biotoxicity, high fluorescence sensitivity, good photostability, and easy modification of the main chain. [22][23][24][25][26][27][28][29][30][31][32] Coumarin derivatives can also be used as fluorescence markers or imaging agents to identify tumor lesions and study the subcellular localization of drugs. [33][34][35][36][37][38][39][40][41][42][43][44] The development of a sensor with high selectivity and sensitivity to copper ions remains an important challenge.…”
