The fluorescence emission of CdSe/ZnS QDs was switched "off" when the native trioctylphosphine oxide ligands were exchanged for 1-(bis(eta(5)-cyclopentadienyl)iron)-methyl-3-(5,7-dimercapto-heptyl)-urea (); importantly, the emission of the resulting conjugate was switched "on" upon addition of fluoride ions.
当将天然的三辛基氧化膦配体换成1-(双(η(5)-环戊二烯基)铁)-甲基-3-(5,7-二巯基庚基)-脲时,CdSe/ZnS量子点的荧光发射被“关闭”;重要的是,加入氟离子后,所得共轭物的发射被“打开”。
