General description
Zinc iodide is a faint yellow solid that absorbs water readily. It is synthesized using metallic zinc with an aqueous iodine solution. It is used as a Lewis acid for organic conversion.
Application
Zinc iodide can be used as:
- An electrolyte in Zinc-iodine redox flow batteries.
- An additive to prepare air-stable cationic lead perovskite films. The addition of ZnI2 enhances the film stability and photoluminescence without affecting the bandgap.
- As a precursor to prepare efficient, eco-friendly, and high color purity inkjet-printed blue InP/ZnS/ZnS quantum dot light-emitting diodes.
- A catalyst in promoting various chemical transformations, for example, in the direct synthesis of 2,3-Dihydroisoxazoles via a [3+2] cycloaddition reaction of the nitrones and terminal alkynes.
- An activator/initiator in living cationic polymerization reactions.
