Chemical structure of iso-butylammonium bromide; CAS No. 74098-36-5; chemical fomula C4H12BrN.

Applications

iso-Butylammonium bromide (iBABr) has applications in perovskite LEDs and solar cells because its branched side-chain helps promote material solubility and device stability. It is believed that the larger iso-butylammonium cation will not fill into the perovskite cage, thus preventing the formation of 3D perovskite structures.
