一般描述

碘是正电性最强、化学活性最低的卤素,但仍可与多种元素形成化合物。这些独特性质令碘成为无数产品和工艺中的关键组分。碘在材料科学中的应用不断增加,例如在有机光伏领域,它可用作太阳能电池的电荷传输材料,提高电池效率。碘还可用于合成先进材料,例如掺碘聚合物,为电子和纳米技术带来创新发展。′

应用

  • 以酮类为氢化物供体的碘促进还原性亚磺酰化。:讨论了一种用碘促进还原性亚磺酰化的新型化学合成技术,强调了碘在创新有机转化中的作用(Duan et al., 2024)。
  • 基于光催化蛋白质邻近标记法的纳米塑料胞内蛋白质电晕成分研究。:本研究采用光催化蛋白质邻近标记法揭示纳米塑料上碘与蛋白质成分之间的相互作用,深入了解了碘与环境的相互作用(Zhang et al., 2024)。
