Descripción general

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.

Aplicación

  • Iodine-Promoted Reductive Sulfenylation Using Ketones as Hydride Donors.: Discusses a novel chemical synthesis technique using iodine to promote reductive sulfenylation, highlighting iodine′s role in innovative organic transformations (Duan et al., 2024).
  • Unraveling Intracellular Protein Corona Components of Nanoplastics via Photocatalytic Protein Proximity Labeling.: This study employs a photocatalytic protein proximity labeling method to examine the interaction between iodine and protein components on nanoplastics, enhancing our understanding of iodine′s environmental interactions (Zhang et al., 2024).
