Oleylammonium Iodide Description

Oleylammonium Iodide (C18H38IN) is an organic ammonium salt composed of the oleylammonium cation (C₁₈H₃₅NH₃⁺) and the iodide anion (I⁻). It is derived from oleylamine, a long-chain fatty amine, and hydroiodic acid (HI), resulting in a salt that is useful in various applications, particularly in nanomaterials and perovskite research.

Oleylammonium Iodide is a critical material used in the fabrication of two-dimensional perovskites for solar cells, LEDs, and surface passivation of nanocrystals. Its unique structure allows for improved material stability, crystallization control, and enhanced optoelectronic properties, making it valuable in advanced material research and next-generation optoelectronic devices.
