Aplicação

Zinc iodide can be used:
  • As an activator to synthesize poly(vinyl methyl ether) via living cationic polymerization. ZnI2 is known to produce living vinyl ether polymerizations.
  • To prepare precursor solutions for lead halide perovskite solar cells. The addition of ZnI2 leads to higher stability against environmental moisture when introduced into perovskite cells.

Hydrothermal reaction of 4,4-trimethylenedipyridine (tmdp) with ZnI2 under 175 degrees C yields a novel compound, {[Zn2I4(tmdp)2]n.[Zn2I4(tmdp)2]n}, which has a chiral infinite double-stranded helical structure consisting of two single-stranded helices of the same handedness.
