Imidazolium bromide, used as electrolytes for DSSC applications

High purity precursor available online for fast, secure dispatch


Imidazolium bromide (ImDBr) is a family member of imidazolium salts that exhibits good electrical conductivity, high ionic mobility, and excellent chemical and thermal stabilities. Imidazolium bromide and its derivatives are also used as electrolytes for dye-sensitised solar cell (DSSC) applications.

Imidazolium bromide also has applications in perovskite solar cells and light-emitting diodes (LEDs).
