A new fluorescence probe based on fluorescein-diarylethene fluorescence resonance energy transfer system for rapid detection of Cd2+

184A novel diarylethene with fluorescein-quinoline unit was synthesized and its multi-controllable fluorescent switching behaviors with light, Cd2+ were investigated systematically. The diarylethene could serve as a highly selective 'turn-on' fluorescence chemosensor for recognition of Cd2+.
