Dimethylammonium bromide (DMABr), CAS 6912-12-5, is an alkylammonium halide salt used as a precursor material in perovskite research. Supplied by Ossila at 98% purity as a powder/crystals, it has the chemical formula C2H8BrN and a molecular weight of 126.0 g/mol.
Because the dimethylammonium cation is larger than many common perovskite cations, DMABr is used to adjust the band-gap and electrical behaviour of perovskite structures. This tuning helps researchers reach high device efficiency and improved long-term stability in hybrid organic-inorganic electronic devices such as perovskite solar cells and perovskite LEDs.
The compound is also known as dimethylamine hydrobromide and N-methylmethanaminium bromide. An MSDS is available from the manufacturer.
