Novel portable coumarin-derived fluorescent probe for highly rapid and selective Cu2+ detection: Versatile applications to environmental monitoring, plant, human serum, and in vivo bioimaging.
A highly rapid and sensitive novel coumarin-derived fluorescent chemosensor, PQTC, was developed and synthesized to selectively detect Cu2+. PQTC having intense yellowish-green fluorescence exhibited rapid response (less than 1 s) and high selectivity to Cu2+ via a fluorescence "turn-off". Limit of detection (LOD) for...
