Thiol-ligand
WebWith increasing amounts of added UDT (100–500 equiv), L-type binding of thiol ligands not associated with Z-type displacement is inferred from comparison of the numbers of each bound and free ligand throughout the 1 H NMR spectroscopic titration. Lastly, a substantial quantity of oleic acid is liberated by the reaction of NCs with 100–500 ... WebDec 23, 2006 · A new and efficient procedure for ligand exchange on core−shell fluorescent nanocrystals is reported. The process involves the reaction of carbon disulfide with a ligand containing an amino group. The resulting dithiocarbamate is strongly bound to the surface of the quantum dots leading to a secure coating of the nanoparticle. The strategy was …
