General description

1-Dodecanethiol is an alkyl thiol that can be used as an organic source of sulfur. It is used in the production of synthetic rubber, nonionic detergent, plastics, and pharmaceuticals.

Application

1-Dodecanethiol (1-DDT) can be used as:      
  • A sulfur source and capping ligand in the synthesis of copper sulfide nanoparticles (Cu2S) which can be applied as electron donor and hole acceptor in photocatalytic reactions.      
  • A coordinating ligand to prepare Cu2ZnSnS4 (CZTS) nanocrystals to control the nucleation and growth of CZTS nanocrystals.

Zinc-doped copper indium sulfide (ZnCuInS2) quantum dots can be functionalized with 1-decanethiol as a ligand to improve the charge mobility and luminance of organic light emitting diodes (OLEDs).
