Abstract
A highly regioselective tetra-ortho-iodination reaction of perylene diimides (PDIs) has been developed, which could be conducted on a multigram scale (>10 g), featuring a column chromatography-free workup and purification. The ortho-iodinated-PDIs serve as key intermediates for the preparation of a variety of ortho-functionalized PDIs and PDI-based conjugated polymers.
摘要
一种高区域选择性的苝二酰亚胺（PDI）的四邻位碘化反应已被开发出来，该反应可在多克规模（>10 克）上进行，具有无需柱层析的后处理和纯化特点。邻位碘化-PDI 可作为制备各种邻位官能化 PDIs 和基于 PDI 的共轭聚合物的关键中间体。
