Abstract

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)-ur ea ( 4); importantly, the emission of the resulting conjugate 5 was switched ``on'' upon addition of fluoride ions.
