摘要：

Functional ligands: The fluorescence intensity of semiconductor nanocrystals (NCs) strongly depends on the energy level arrangement of the nanocrystals (the valence band (VB) and conducting band (CB)) and their molecular ligands. Using a functional ligand such as 1, where the oxidation potential can be adjusted by metal-ion complexation, the fluorescence of the nanocrystals can be used for metal ion recognition.
