Chemical Structure

iso-Butylammonium-iodide, ibai

Chemical structure of iso-butylammonium iodide; Chemical fomula: C4H12IN.


Like other alkylammonium halides, iso-butylammonium iodide (iBAI) is used to tune perovskite structures to achieve the desired size of perovskite grains and nanoplates for LED and solar cell applications.

With a branched side-chain,  iso-butylammonium iodide promotes solubility and hinders the growth of 3D perovskite structures - helping you to achieve device performance stability.
