Description

General description

Iodine is the most electropositive halogen and the least reactive, yet it can still form compounds with a variety of elements. These unique characteristics make iodine an essential component in numerous products and processes. In the field of material science, iodine is increasingly utilized in applications such as organic photovoltaics, where it enhances the efficiency of solar cells by serving as a charge transport material. Additionally, iodine′s role in the synthesis of advanced materials, such as iodine-doped polymers, opens avenues for innovations in electronics and nanotechnology.
