t-Butylammonium bromide (tBABr), CAS 60469-70-7, is an alkylammonium halide supplied by Ossila as a high purity perovskite precursor with a purity of ≥ 98%. It is offered as a powder or crystals with the formula C4H12BrN and a molecular weight of 154.05 g/mol.
Its bulky tert-butyl group makes it a useful additive for modifying perovskite structures. Incorporating tBABr helps improve material solubility and device stability, since the resulting perovskites are less sensitive to moisture than 3D methylammonium-based perovskites.
When precursors carrying bulky alkyl groups are included, plate-like 2D-phase crystallites have been observed standing between the 3D perovskite grains, and the crystallinity of the film is markedly improved. This makes tBABr relevant to research on perovskite solar cells and perovskite LEDs.
- Precursor for modifying perovskite structures with a bulky tert-butylammonium cation.
