General description

Copper(I) bromide is a faint green inorganic diamagnetic solid that has a polymeric structure like zinc sulfide. It is insoluble in water and widely used in the field of catalysis, nanomaterial synthesis, and solar cells.

Application

Copper(I) bromide can be used:
  • As a solution-processable hole transport layer (HTL) for organic solar cells (OSCs). CuBr enhances the power conversion efficiency of solar cells.
  • As a precursor to synthesize photoluminescent metal organic frameworks(MOFs).
  • To synthesize highly emissive three-coordinate copper(I) complexes as a dopant in OLEDs with maximum external quantum efficiency of 21.3%.
  • As a catalyst with ligands for atom transfer radical polymerization (ATRP) reaction of tertiary alkyl halides in 14 different solvents to determine the rate constant.
  • To synthesize macrocyclic polymer via intramolecular radical trap-assisted atom transfer radical coupling.
