iso-Butylammonium bromide, often abbreviated iBABr, is an alkylammonium halide used as a precursor material in perovskite research. Ossila supplies it with a purity of ≥ 98% in powder/crystal form, with CAS number 74098-36-5, chemical formula C4H12BrN and a molecular weight of 154.05 g/mol.
The compound is of interest for perovskite light-emitting diodes and perovskite solar cells. Its branched iso-butyl side-chain helps improve the solubility of the material and supports better device stability. Because the iso-butylammonium cation is relatively large, it is thought to be unable to fit inside the perovskite cage, which prevents a 3D perovskite structure from forming.
The material is also known as iso-butanamine hydrobromide and iso-butanaminium bromide.
- Precursor material for fabricating perovskite light-emitting diodes.
- Additive or precursor in perovskite solar cell research aimed at improving device stability.
- Improving the solubility of perovskite precursor formulations through its branched side-chain.
- Research on suppressing the formation of 3D perovskite structures using a large organic cation.
