| Application: | Zinc iodide can be used: • As a catalyst for one-pot synthesis of aminoindolizines via sequential A3 coupling/cycloisomerizati • As a catalyst for one-pot synthesis of quinoxalines. • As a precursor to synthesize highly luminescent quantum dots. • As a redox electrolyte in hybrid energy storage systems. • As a dopant to prepare highly flexible PVA composite films. The addition of zinc iodide enhances the optoelectronic properties of polymer composite. |
| General description: | Zinc iodide is a white crystalline Lewis acid often used as a starting material for synthesizing other zinc compounds, as a Lewis acid catalyst in organic reactions, and as an electrolyte additive. |
