Direct Synthesis of Large-Scale <i>Ortho</i>-Iodinated Perylene Diimides: Key Precursors for Functional Dyes Jiajun Wu Dezhi He Li Zhang Yudong Liu Xiaogang Mo Jianbin Lin Hui-jun Zhang 10.1021/acs.orglett.7b02718.s001 https://acs.figshare.com/articles/journal_contribution/Direct_Synthesis_of_Large-Scale_i_Ortho_i_-Iodinated_Perylene_Diimides_Key_Precursors_for_Functional_Dyes/5450872 A highly regioselective tetra-<i>ortho</i>-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 <i>ortho</i>-iodinated-PDIs serve as key intermediates for the preparation of a variety of <i>ortho</i>-functionalized PDIs and PDI-based conjugated polymers. 2017-09-28 14:48:43 Functional Dyes perylene diimides functionalized PDIs Key Precursors regioselective tetra Large-Scale Ortho Perylene Diimides iodination reaction ortho Direct Synthesis column chromatography-free workup
