Popis

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).
