애플리케이션

Selenourea [(SeC(NH2)2)] has been used as a selenium (Se) precursor for the insertion of Se into protein crystals.
It can also be used as a reagent to synthesize:
  • Selenazoles from α -bromo ketones presence of β -cyclodextrin.
  • Symmetrical diaryl selenides by C-Se cross coupling reaction in presence of coper oxide nanaoparticles as a catalyst.
  • CdSe nanocrystals.

We report a general strategy for obtaining high-quality, large-area metal-chalcogenide semiconductor films from precursors combining chelated metal salts with chalcoureas or chalcoamides. Using conventional organic solvents, such precursors enable the expeditious formation of chalco-gels, which are easily transformed into the

Herein we report on the use of different metal precursors in the synthesis of MoSe2 nanomaterials in order to control their morphology. The use of Mo(CO)6 as the metal precursor resulted in the formation of wrinkled few-layer nanosheets, while the
