Nanocrystalligand exchange with 1,2,3,4-thiatriazole-5-thiolate and its facile in situ conversion to thiocyanate

Abstract

The 1,2,3,4-thiatriazole-5-thiolate anion (TTT) was found to be a strongly binding ligand for CdSe nanocrystals, quantitatively exchanging various long-chain ligands to yield stable colloidal suspensions in common polar solvents. The TTT ligand thermolyzes at <100 °C to produce thiocyanate in situ, resulting in reduced quantum confinement in nanocrystal films. CdSe(TTT) possesses far higher colloidal stability than CdSe(SCN), and that, together with the facile synthesis of TTT, implies that this is a useful ligand for nanocrystal applications as a masked thiocyanate.
