contrast to the traditional multistep synthesis, herein an efficient and fewer‐steps new synthetic strategy is demonstrated for the facile preparation of organic‐electronically important D–π–A–π–D‐type oligoaryls through sequential direct CH arylations. This methodology has shown that the synthesis of thieno[3,4‐c]pyrrole‐4,6‐dione (TPD)‐ or furano[3,4‐c]pyrrole‐4,6‐dione (FPD)‐centred target molecules
与此相反的传统多步合成,本文中的高效和少数步骤新的合成策略是证明了通过顺序直接C中容易制备的有机电子重要d-π-A-π-d型oligoaryls ħ芳基化。该方法学表明,以噻吩并[3,4- c ]吡咯-4,6-二酮(TPD)或呋喃并[3,4- c ]吡咯-4,6-二酮(FPD)为中心的目标分子的合成可以从核心结构(受体)或末端结构(供体)经济地步入,这为π功能小分子半导体材料的制备提供了更灵活,更简洁的新合成替代品。另外,检查了合成的低聚芳基的光学和电化学性质。
