Application

Guanidinium bromide (GBr) can be used in the functionalization of poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) for the formation of the anion exchange membrane for fuel cells applications. It can also be used in the preparation of an amphiphilic catalyst for the production of biodiesel.
Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors with extremely low water contents are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.

Caution

  • Extremely hygroscopic.
  • Handle in glove box.
  • Handle and store under nitrogen atmosphere.
